The sentence in which the pronoun has been used incorrectly is:
C. Jack likes baseball as much as me.
Explanation:
A pronoun is the part of speech which is used in the place of a noun. The use of pronoun helps in a smoother and clear framing of the sentence. Once the noun is used, the place of the noun is taken by the pronoun in the sentence. In the third sentence, instead of using the pronoun 'I', the pronoun 'me' will be used in the sentence to correct formation of the sentence.
