Answer: pronoun is the answer
Explanation:
An Explanation in Simple Terms. In English grammar, an antecedent is a subject that will be renamed by another word later in a sentence. Most often the word replacing the antecedent is a pronoun, though it can also be a noun or noun phrase
The correct answer should be Ron and She.
That is because her is an object pronoun, therefore should be used as an object. Ron and She are a subject and therefore she is correct.
