Concept: A clause that describes a noun and lacks its own subject begins with a relative pronoun.
- “___ promises to … create anything” has a verb but no subject.
- 'That' refers back to 'technology' and acts as the subject: “a technology that promises…”.
- 'Than' is for comparison, 'then' for time, 'the' is an article.
Trick: Replace the blank with 'which' — if it fits, 'that' is right.
Answer: (B) that
अवधारणा: संज्ञा का वर्णन करने वाला उपवाक्य, जिसका अपना कर्ता न हो, relative pronoun से शुरू होता है।
- रिक्त के बाद “promises to create…” में क्रिया है, कर्ता नहीं।
- 'That' यहाँ 'technology' की ओर इशारा करता है और कर्ता का काम करता है।
- 'Than' तुलना, 'then' समय और 'the' article है।
ट्रिक: रिक्त में 'which' रखकर देखें — बैठे तो 'that' सही।
उत्तर: (B) that
