Which of the following sentences uses a collective noun with correct verb agreement?

a. the team returns at about four o'clock this afternoon.
b. we will attack until the enemy are in retreat.
c. the committee are voting this afternoon.
d. your group are unable to decide on an effective presentation method.

It would not be D! IF d was correct it would say "Your group IS unable to decide on an effective presentation method." The correct answer is A. "The team returns at about four o'clock this afternoon." 
The best way to find the answers for these types of questions is to read them aloud and see which one sounds correct and as you would normally say it and then they're typically easier to understand. Hope this helps!
