B. adjective clause

The group of words "who gives the hardest tests" is an adjective clause because it contains a subject ("who") and a verb ("gives") and gives more information about "The teacher." It is not just a phrase, since it includes a subject and a verb and is dependent on the main clause for its meaning.
