The 'pronoun-antecedent agreement' says that the pronoun must agree with the antecedent in number and person. Therefore, the singular pronouns must carry a pronoun-antecedent and a singular pronoun employ a singular antecedent.
As per the question, the choice that correctly features a 'pronoun-antecedent agreement' would be option C as it appropriately employs singular pronoun 'his' with the singular antecedent 'neither' and therefore, exemplifies the agreement. Thus, <u>option C</u> is the correct answer.
