Respuesta :
We weren't sure how to feel about this, the all-important decision. is correctly punctuated
Answer:
C
Explanation:
Since the conjunction in this section is past tense and is structured like this:
We weren't sure how to feel about this; the all-important decision.
Instead of this:
We aren't sure how to feel about this all-important decision.
C is the only grammatically correct answer.
