The term that describes a group of words containing a subject and its verb is a clause. To identify a clause, you need to look for a subject, which is the noun or pronoun that the sentence is about, and a verb, which is the action or state of being. A clause can stand alone as a sentence or be a part of a larger sentence. So, the correct answer is "a clause."
