In the question below, two columns of phrases are provided—Column I and Column II. Choose the pair that, when joined with the given connector, forms a grammatically correct and contextually meaningful sentence.

Column I	Column II
A. The hall fell silent,	D. ___ she would wake up before sunrise.
B. The instructions were printed clearly,	E. _____ even the last row could read them.
C. Ravi revised the rules again,	F. ______everyone could hear the speaker without strain.

Correct option is C

Correct answer: (c) A–F (so that)
Why:
· A–F: “The hall fell silent, so that everyone could hear the speaker without strain.” Grammatically sound and contextually logical (purpose/result).
· (a) B–F with “so”: “The instructions were printed clearly, so everyone could hear the speaker…” Mismatch of ideas (instructions vs hearing).
· (b) C–E with “therefore”: “Ravi revised the rules again, therefore even the last row could read them.” Awkward causation; revising rules doesn’t affect legibility.
· (d) B–D (within); A–F (for): Not a valid single pairing; also “within/for” don’t fit D or F properly.
· (e) B–E with “but”: “but” shows contrast; here both clauses are positive and should use a result/purpose connector, not contrast.
