Identify the sentence using the indicated pronoun correctly. whom as an interrogative pronoun Whom did you forget to call? Whom is your friend?

The correct answer is: Whom did you forget to call?

The sentence that uses whom correctly is "Whom did you forget to call?"

Explanation:

"Whom" should be used to refer to the object of a verb or preposition. In order to be sure as regards when to use who or whom, you can do a test. If you can replace the word with "he" or "she", you should use "who". If you can replace it with "him" or "her", use "whom". "Who" is not used to refer to the object of a verb or preposition but to the subject.

In this case, "whom" functions as the object of the verb.
