I think we can not use that in this case, because according to the meaning of the sentence, we need a preposition, right? So only D and E. I'm confused with those two answers. Should use which or what? The OA is E. It means "what" is used in this case. But I don't understand why we don't use "which". I think "at which" is correct

the drug's maker charges ( some price) for another product with the same active ingredient => usage of that is apt

IMO C
