Concept: Seleucus Nicator sent his ambassador to the Mauryan court at Pataliputra after his treaty with Chandragupta Maurya.

1. The ambassador was Megasthenes, who wrote Indica describing Mauryan administration and Pataliputra.
2. Ptolemy, Strabo and Pliny were later geographers/writers, not ambassadors to Chandragupta.

Yaad rakhein: Megasthenes → Indica → Chandragupta; Deimachus → Bindusara.

Answer: (A) Megasthenes

Concept: Real GDP growth of India in 2023-24 was estimated at 9.2% (revised estimates of NSO).

1. This was the highest in 12 years, except 2021-22 (when growth was about 9.7% due to the post-COVID base effect).
2. 6.2% and 5.2% are too low, and 15.2% is unrealistic for a full year.

Yaad rakhein: 2023-24 → 9.2%; only 2021-22 (post-COVID rebound) was higher.

Answer: (B) 9.2%

Concept: Freon-12 is dichlorodifluoromethane (${\text{CCl}}_2{\text{F}}_2$), a chlorofluorocarbon (CFC).

1. It is manufactured industrially and was widely used as a refrigerant in ACs/refrigerators and as an aerosol propellant.
2. CFCs release chlorine in the stratosphere and deplete the ozone layer, so they are being phased out under the Montreal Protocol.

Yaad rakhein: Freon = CFC = refrigerant + aerosol + ozone depletion.

Answer: (D) Freon-12

Concept: The eastern extension of the Himalayas, beyond the Dihang gorge, is called the Purvanchal (Eastern Hills).

1. Purvanchal includes the Patkai Bum, Naga Hills, Manipur Hills and Mizo (Lushai) Hills.
2. The Khasi Hills (with Garo and Jaintia) belong to the Meghalaya (Shillong) Plateau, an extension of the Peninsular Plateau — not the Himalayas.

Yaad rakhein: Garo–Khasi–Jaintia = Meghalaya Plateau (peninsular); Patkai–Naga–Mizo = Purvanchal (Himalayan).

Answer: (A) Khasi Hills

Concept: After supplying BrahMos (2022 deal), India in early 2025 was expected to finalise a further defence export deal worth over $200 million with the Philippines.

1. Reports named the Akash surface-to-air missile system for this deal.
2. Akash is an indigenous short-range SAM developed by DRDO and made by Bharat Dynamics Ltd.
3. BrahMos was already contracted by the Philippines in 2022 (about $375 million), so it is not the new deal.

Yaad rakhein: Philippines: BrahMos = 2022 deal; Akash = new 2025 deal.

Answer: (B) Akash Surface-to-Air Missile

Concept: NFHS-5 (2019–21) reported child nutrition indicators for children under 5 years.

1. Underweight: 32.1%; Stunted: 35.5%; Wasted: 19.3%.
2. 19.3% (option A) is the wasting figure — a common trap.

Yaad rakhein: NFHS-5: Stunting 35.5 > Underweight 32.1 > Wasting 19.3.

Answer: (B) 32.1%

Concept: The National Human Rights Commission (NHRC) is a statutory body set up on 12 October 1993 under the Protection of Human Rights Act, 1993.

1. Its headquarters is Manav Adhikar Bhawan, INA, New Delhi.

Concept: A cell address is written as Column letter followed by Row number.

1. In B5, “B” is the column (2nd column) and “5” is the row.
2. So B5 is the cell where column B meets row 5.

Yaad rakhein: Excel: Letters = Columns, Numbers = Rows.

Answer: (D) Column B and Row 5

Concept: The Naikda (Naikdas) uprising of 1858 took place in the Panchmahals–Sankheda region of present Gujarat (around today’s Chhota Udepur district).

1. The Naikdas rose under Rupa Naik and Kewal Naik and used guerrilla tactics, attacking British police posts (thanas).
2. Rupa Naik surrendered to the British in 1859 under an offer of amnesty, not in 1860 — so statement D is not correct.

Yaad rakhein: Naikda revolt: 1858, Panchmahals/Sankheda, leaders Rupa & Kewal; surrender in 1859.

Answer: (D) The leader Rupa surrendered before the British in 1860.

Concept: In a transverse wave, particles of the medium vibrate perpendicular to the direction in which the wave travels.

1. When a stretched string is plucked, each part of the string moves up–down while the disturbance travels along the string.
2. So the wave on a string (sitar, guitar, violin) is a mechanical transverse wave.

Yaad rakhein: String = transverse; sound in air = longitudinal.

Answer: (D) Transverse wave

Concept: The Directorate General of Civil Aviation (DGCA), under the Ministry of Civil Aviation, is India’s civil aviation regulator.

1. It handles safety regulation, licensing of pilots and aerodromes, airworthiness and certification of airports, i.e. the regulatory side of aviation infrastructure.
2. The Airports Authority of India builds, operates and manages airports — it is an operator, not the regulator.

Yaad rakhein: DGCA = regulator (rules, licences); AAI = operator (runs airports).

Answer: (B) Directorate General of Civil Aviation

Concept: The Ramoshis were a community of the Western Ghats (Maharashtra) who had served the Marathas as hill-fort guards and village watchmen.

1. After the fall of the Peshwas (1818), British rule left them without work, leading to the Ramoshi uprising (1822, under Chittur Singh; 1825–26 under Umaji Naik).
2. Hence they guarded the forts of the Marathas.

Yaad rakhein: Ramoshi → Maratha forts → Umaji Naik.

Answer: (D) Marathas

Concept: The Kakatiya Rudreshwara (Ramappa) Temple at Palampet, Mulugu district, Telangana, was inscribed as a UNESCO World Heritage Site in 2021.

1. It was built in 1213 CE under Kakatiya ruler Ganapati Deva by general Recharla Rudra; it is named after its sculptor Ramappa.
2. Its bricks are so light that they float on water.

Yaad rakhein: Ramappa = Telangana = 2021 (India’s 39th WHS).

Answer: (A) Telangana

Concept: Vitamin A (retinol) is needed to make rhodopsin, the light-sensitive pigment of rod cells in the retina.

1. Rods work in dim light; low rhodopsin causes night blindness (nyctalopia), and later xerophthalmia.
2. Vitamin C → scurvy, B12 → pernicious anaemia, D → rickets.

Yaad rakhein: A for “Aankh” (eyes): Vitamin A → night blindness.

Answer: (B) Vitamin A

Concept: The World Bank’s State of Social Protection Report 2025 (“The 2-Billion-Person Challenge”) reviewed social protection coverage in developing countries.

1. It noted that during COVID-19, emergency social protection responses reached about 1.7 billion people.
2. The report highlights that about 2 billion people in developing countries still lack any social protection coverage.

Yaad rakhein: COVID response reach = 1.7 billion; still uncovered ≈ 2 billion.

Answer: (B) 1.7 billion

Concept: Under the Liberalised Remittance Scheme (LRS), Tax Collected at Source (TCS) applies on foreign remittances above a threshold.

1. Budget 2025-26 raised this TCS threshold on remittances under LRS from ₹7 lakh to ₹10 lakh.
2. It also removed TCS on education remittances financed by loans from specified financial institutions.

Yaad rakhein: LRS-TCS: 7 → 10 lakh (Budget 2025).

Answer: (B) ₹10 lakh

Concept: In Windows, pressing Delete on a file does not erase it immediately.

1. The file is moved to the Recycle Bin, from where it can be restored.
2. It is permanently erased only when the Recycle Bin is emptied, or when Shift + Delete is used.

Yaad rakhein: Delete → Recycle Bin; Shift + Delete → permanent.

Answer: (C) The Recycle Bin

Concept: The IMF World Economic Outlook Update of January 2025 projected global growth at 3.3% for both 2025 and 2026.

1. This is below the historical (2000–19) average of 3.7%.
2. In the same update India’s growth was projected at 6.5% for 2025-26.

Yaad rakhein: IMF Jan 2025: World 3.3%; India 6.5%.

Answer: (B) 3.3%

Concept: PMAY-Urban 2.0 (approved 2024) aims to provide 1 crore urban houses; it includes a Technology & Innovation Sub-Mission (TISM).

1. TISM supports the use of innovative, green, disaster-resilient and energy-efficient construction technologies and housing designs suited to different geo-climatic zones.
2. Housing loans with interest subsidy are a separate component (Interest Subsidy Scheme), not TISM.

Yaad rakhein: TISM = Technology → new, green, sustainable building methods.

Answer: (B) It is focused on promoting green building techniques and energy-efficient housing designs across geo-climatic regions.

Concept: Cache is a small, very fast memory (usually SRAM) between the CPU and main memory (RAM).

1. It stores frequently used data/instructions, is faster than RAM, and is located inside or very close to the CPU (L1, L2, L3).
2. It is volatile primary-side memory, not secondary storage (like HDD/SSD). So statement A is incorrect.

Yaad rakhein: Speed order: Registers > Cache > RAM > Secondary storage.

Answer: (A) Cache memory is a form of secondary storage.
