Explanation:

A pronoun is a word that renames a noun within a sentence; it can be personal, like you, me, she, they, etc; demonstrative, like that, those, etc; interrogative, like who, what, which, and many more. An antecedent is the word (usually a noun) that the pronoun refers to; it is usually placed before the pronoun within a sentence.

However, in sentence C, you can see that the pronoun she is placed before the antecedent girl that it refers to. This does not happen in the other examples.
