The question is asking for the term that refers to the part of a sentence that provides information about the subject. The correct answer is 'A. Predicate' because it is the part of a sentence that tells what the subject does or is. 'B. Subject' is the part of a sentence about which something is stated, which is not the focus of the question. 'C. Object' receives the action of the verb, which is not the part that gives information about the subject. 'D. Complement' is used to complete the predicate by giving more information about the subject or object, but it is not the main part that provides information about the subject.
