When would you be most likely to use an interrogative pronoun?

a.) to introduce a question
b.) to add emphasis to a noun or a pronoun
c.) to introduce an adjective clause
d.) to direct attention to a specific person, place, or thing

The correct answer is A. An interrogative pronoun is most likely used to introduce a question. The word "interrogative" means "relating to a question," so an interrogative pronoun must be a pronoun that relates to a question. Remember that interrogative pronouns are what, which, who/whom, and whose. These pronouns are used to ask questions. For example: Which book is mine? Who is at the door? What time do we have to leave?
