Question

Which personal pronoun agrees with the antecedent in this sentence? One of the boys remembered to bring __________ camera on the hiking trip. A. his B. your C. our D. their

Answer 1

A because are using one and that means singular

Answer 2

Since the pronoun is supposed to represent "one of the boys" the answer is A. his. You want a singular pronoun so it wouldn't be C or D. B might fit but it does't make sense since we're assuming the boy was bringing his own camera.
