When muslims speak of "people of the book," to whom are they referring?

Christians

Explanation: The term "People of the Book" is an Islamic term to refer to all Christians. It can also apply to Jews. The term was developed due to the fact that both Jews and Christians have a monotheistic belief that is based on the Old (Torah) and the New Testaments. The term has also been adopted by Jews and Christians to refer to themselves.
