The sentence that does not contain an antecedent is:

"Amelia studied for her biology exam while babysitting."

An antecedent is a word, usually a noun, that a pronoun refers back to in a sentence. In this sentence, there are no pronouns that need an antecedent; "Amelia" is a proper noun, and "studied for her biology exam while babysitting" are actions she performed, not referring back to any noun with a pronoun.
