Which sentence has correct pronoun and antecedent agreement?

She handed the papers to her supervisor after reviewing them herself.

The sentence that has correct pronoun and antecedent agreement is:

"Heather washed her car before going to the store."

Explanation:
In this sentence, the pronoun "her" agrees with the antecedent "Heather," indicating that Heather washed her own car.

To identify which sentence has correct pronoun and antecedent agreement, we need to find a sentence where the pronoun agrees in number and gender with its antecedent.

An antecedent is the word, phrase, or clause that a pronoun refers to. Pronouns must agree with their antecedents in three ways: number (singular or plural), gender (masculine, feminine, or neuter), and person (first, second, or third).

Let's look at some examples:

1. "The student handed in their homework." - This sentence uses the plural pronoun "their" to refer to the singular antecedent "student." The pronoun and antecedent do not agree in number, so this sentence has incorrect pronoun and antecedent agreement.

2. "Emily loves her cat, and she takes care of it." - Here, the pronoun "she" agrees in number (singular) and gender (feminine) with the antecedent "Emily." Additionally, the pronoun "it" agrees in number (singular) with the antecedent "cat." Therefore, this sentence has correct pronoun and antecedent agreement.

Based on these examples, the sentence "Emily loves her cat, and she takes care of it" has correct pronoun and antecedent agreement.
