In which of the following sentences does the pronoun agree with its antecedent?

The correct choice demonstrates concord between the pronoun and its antecedent by ensuring that the singular antecedent aligns with a singular pronoun. In this case, "the team's captains" refers to multiple individuals, but "they" is used correctly as a plural pronoun that refers back to "captains."

The other choices illustrate various forms of disagreement. In the first choice, "No one" is a singular indefinite pronoun, yet it is followed by the plural pronoun "their," causing a mismatch. The second choice uses "the panel," which is a collective noun and can often be treated as singular, but the plural pronoun "they" suggests multiple entities, creating ambiguity in interpretation. The last choice features "Each collaborator," a singular phrase, incorrectly paired with the plural pronoun "their." Thus, the correct response demonstrates a clear agreement in number, ensuring grammatical accuracy.
