Right.

To determine which sentence has a pronoun and antecedent that agree in number and person, we need to identify the pronouns and their antecedents in each sentence.

1. "Our neighbors are celebrating his son's birthday today."
In this sentence, there is a disagreement in number and person. "Neighbors" is plural, while "his" is singular. Therefore, this sentence does not have pronoun-antecedent agreement.

2. "My mom gave me a new book because they have an interesting plot twist."
In this sentence, "they" is the pronoun and it refers to the antecedent "book." Both the pronoun and antecedent are in the plural form, indicating agreement in number. However, there is a disagreement in person because "they" (third person) is used to refer to "me" (first person). As a result, this sentence does not have pronoun-antecedent agreement.

3. "My cousin is getting married, and she is very excited."
In this sentence, the pronoun "she" correctly agrees in both number and person with the antecedent "cousin." Both are singular (third person), which ensures pronoun-antecedent agreement. Therefore, this sentence is the one that has a pronoun and antecedent that agree in number and person.

4. "Kerry and Sarah wanted to get a pizza, but she did not agree on the toppings."
In this sentence, there is disagreement in both number and person. "Kerry and Sarah" is plural (they), while "she" is singular (third person). Thus, this sentence does not have pronoun-antecedent agreement.
