Which personal pronoun agrees with its antecedent and correctly completes the sentence?
each child was allowed to pick out clothes for the day.
a. your
b. our
c. their
d. his or her

C because it tells the readers that the children picked out their own clothing. The sentence didn't specify on the gender so it wouldn't be D. The children aren't picking out your clothing, that sounds weird so it wouldn't be A. They aren't picking out our clothing so it isn't B.
