Choices

6

Choice-A

"But" is a coordinating conjunction, so it can’t start a sentence fragment like this. It results in two improperly joined clauses.

Wrong No change

7

Choice-B

"Since" correctly introduces a dependent clause explaining the reason. It shows cause and effect, making the sentence complete and grammatically correct.

Correct Since

8

Choice-C

"To" is not a conjunction and cannot join two full clauses. The sentence becomes grammatically incorrect.

Wrong To

9

Choice-D

"For" as a conjunction implies reason but needs proper structure (e.g., "She stayed home, for she was unwell"). Here, it creates a fragment.

Wrong For
