Which sentence demonstrates correct pronoun-antecedent agreement?

• A. his
• B. their
• C. her
• D. its

Answer: (B)

Pronoun-antecedent agreement means the pronoun must match the number of the noun it refers to. If the antecedent is plural, the pronoun should be plural. Using their is appropriate because it treats a plural antecedent (like students, children, teams) with a plural pronoun.

For example: The students forgot their homework. Here, students is plural, so their is correct.

His and her are singular pronouns and would match a single person, not a plural antecedent. Its is also singular and is used for a single object or animal, not for a plural noun. Therefore, the sentence with their best demonstrates correct pronoun-antecedent agreement.
