Well, considering I don't know what the whole article is about, I'm going to take my best educated guess in hopes that it will be of use to you.
First, I can probably uliminate answer B. because stating a fact, doesn't usually mean that many disagree with him/her.
D. Is fairly similiar to the previous option, and a key to multiple choice questions, if usually taking away the ones most alike.
That leaves you with options A and C.
If it were me, I'd go with option, A.
Hope this helps!
