The sentence that contains an adverb clause is D: "Before we got started, we realized we didn't have time". Adverb clauses are clauses that function as an adverb in a sentence. What is more, they are used to add explanatory details as regards how or why things happen.

Adverb clauses are dependent clauses. As such, they should have a subordinating conjuction to connect them to the rest of the sentence. In this case, a when clause introduced by the conjuction "before" is the adverb clause.
