D. A clause has a subject and verb, but a phrase does not.

Explanation: Clauses and phrases are differents parts of sentence, and it is important to know the differences between them. A clause is a group of words that consists of a subject (the one that performs the action of the verb) and a verb (the action), a phrase doesn't have a subject or a verb, it consists basically of modifiers. A clause and a phrase can be both on a sentence for example: the boy seats on the chair, "the boy seats" is the clause and "on the chair" is the phrase.
