An adjective clause (also known as a relative clause) is a dependent clause that modifies a noun or pronoun in the main clause, often introduced by a relative pronoun like "who," "which," or "that."

• Sentence (B): "I know the man who built that house."
  The clause "who built that house" modifies the noun "man" and describes which man is being referred to, making it an adjective clause.
