Answer:
The answer to your question would be that the sentence that contains a nonessential adjective clause is the following one: The officials revised the rules, which the coach explained to us before the practice.
Explanation:
The sentence above contains a nonessential relative clause introduced by the relative pronoun <em>which.</em> The clause is nonessential because the information it provides is not relevant to complete the meaning of the sentence.
