Which of the following sentences demonstrates proper pronoun-antecedent agreement?

The correct sentence demonstrating proper pronoun-antecedent agreement is Option C: 'If a person wants to travel to the moon, she must get a job at a space technology station.' In this sentence, the pronoun 'she' correctly agrees with the singular antecedent 'a person,' maintaining proper pronoun-antecedent agreement. Options A, B, and D fail to exhibit correct agreement. Option A uses 'he,' which does not correspond with the plural antecedent 'people.' Option B uses 'you,' which is inconsistent with the singular antecedent 'a person.' Option D also uses 'you,' which does not match the plural antecedent 'people.' Therefore, Option C is the only choice that demonstrates the correct pronoun-antecedent agreement.
