Which word commonly introduces an adjective clause?

• A. That
• B. Because
• C. If
• D. When

Answer: (A)

A relative pronoun that starts an adjective clause—the part of the sentence that describes a noun. Adjective clauses tell us more about a noun and are introduced by words like that, which, who, or whom. Among the options, that is the one that commonly signals an adjective clause. For example: The report that I wrote earned praise. The phrase “that I wrote” describes which report, and it’s introduced by that. The other options introduce different kinds of subordinate clauses. Because starts a clause that explains reason (I stayed home because it was raining). If introduces a condition (If it rains, we’ll cancel). When introduces time (We’ll leave when the bus arrives). These are not adjective clauses because they don’t describe a noun.
