Answer:
The answer Is B. Something.
A dependent clause cannot stand on its own. A clause means that it has a finite verb, meaning that there are no infinitives and participles/gerunds only, but a finite verb.
Having that in mind, the dependent clause here would be D. who works at that desk, which means that the rest of the sentence - <em>The woman is absent today </em>is independent.
The correct answer would be D. While the team made their play, the frenzied crowd cheered them to victory.
Hope this helps!
