Explanation:
Whom is an objective pronoun that is used for formal English. It is used as the object of a verb or preposition. Whom should replace the object of the sentence.

Who is used to provide more information about a person or people mentioned previously in a sentence. It is also a subjective pronoun. A subjective pronoun is a pronoun (I, me, he, she, etc.) that is used as the subject of the sentence. Who replaces the subject of the sentence.
