Which personal pronoun correctly completes the sentence?



their


its


his or her


his

Verified Answer :

Each of the singers in the boys' choir must practice his part.

They are all members of a boys' choir so the answer would be 'his'. 
It cannot be his or her because there are no girls in the situation. "It's" doesn't apply to a person. 

The answer is his.
