Concept: Arrange process steps in the order they actually happen.
- P – specimen introduced and placed on the slide (start).
- Q – dye applied to the sample.
- R – cover slip lowered to secure it.
- S – slide placed under the lens (final step).
Trick: 'The specimen' is introduced only in P; 'then' in S marks the last step → P _ _ S, only (B) fits.
Answer: (B) P, Q, R, S
अवधारणा: प्रक्रिया के चरण उसी क्रम में रखें जिसमें काम होता है।
हल:
- P – नमूना तैयार कर slide पर रखा (शुरुआत)।
- Q – रंग (dye) डाला गया।
- R – cover lowered किया गया।
- S – slide को lens के नीचे रखा (अंतिम)।
ट्रिक: नमूने का परिचय केवल P में; S में 'then' – अंत। P _ _ S केवल (B) में।
उत्तर: (B) P, Q, R, S
