I know why option A and option C are incorrect. My problem is with options B and D.
The correct answer is option D but I don't understand why option B is ungrammatical or even less favorable. If my understanding is correct, because the second clause has no verb it is a dependent clause. If it did however have a verb only option B would be correct because it would be the only dependent clause because of the relative pronoun whom. Why does omitting the verb make it not work?
