Which sentence demonstrates correct pronoun-antecedent agreement? Shyanne wants to know if their coat will be warm enough to wear this winter. Either the neighbor or the mail carrier left their hat lying in the yard. Levi and Yani decided to take their names out of the election for club president. All the kids on the playground stopped what he and she were doing to watch.

Levi and Yani decided to take their names out of the election for club president.

Explanation:

A pronoun-antecedent is the use of a pronoun for the earlier noun or pronoun. The antecedent is the word for which the replaced pronoun stands for.

From the given sentences, the one that contains a pronoun-antecedent is the third sentence. In this sentence, the nouns "Levi and Yani" are replaced by the pronoun "their". so, "Levi and Yani" is the antecedent for the pronoun "their".

Thus, the correct answer is the third option.
