Questions: How can you determine whether to use who or whom in a relative clause? Select two answers. Whom is used as a subject. Who is used as a subject. Who is used as an object. Whom is used as an object.

The answer is:

• Who is used as a subject.
• Whom is used as an object.

This is incorrect. "Whom" is not used as a subject; it is used as an object.

This is correct. "Who" functions as the subject of a verb in a relative clause. For example, "The person who called you is my friend."

This is incorrect. "Who" is not used as an object; "whom" is used in this role.

This is correct. "Whom" functions as the object of a verb or preposition in a relative clause. For example, "The person whom you called is my friend."
