Answer:
C. A clause has a subject and verb, but a phrase does not.
Explanation:
Phrases and clauses are the two important parts of the sentences. A clause is the part of the sentence which includes a subject and a verb. On the other hand, a phrase is the part of the sentence which does not include a subject and a verb. The meaning of the clause is complete while the phrase does not stand alone or give complete meaning. A phrase complements the structure of the sentence. Both the clause and the phrase exists in the same line.
