Answer:
C. antecedent
Explanation:
An antecedent is a word, phrase or clause that a pronoun refers to. In sentences, there should always be a pronoun-antecedent agreement, otherwise, the idea of the sentence would be confusing. Take a look at the following sentence:
Mary has never been easy on me, she's always judging me, no matter what.
Here, there is a pronoun-antecedent agreement because the personal pronoun “She” clearly refers to the antecedent “Mary.”
