Step-by-step explanation:

An adjective clause is a clause including one or more adjectives, which qualifies a noun. An adjective clause starts with a relative pronoun (such as who, that, which) or a related adverb (who, where, when). An adjective clause is a dependent clause that, like an adjective, qualifies a noun or pronoun.
