Hm, I think I understand now.
Choice B is stating that both passages claim there IS a difference between animal vs. human communication, and the issue between them is determining, "Okay, but how much of a difference?". This doesn't really support what's presented in B's argument. The author doesn't agree with there being a distinct difference and that the issue is just determining how far this difference goes, but B says there might not be an essential difference at all. (Lines 60-62).
Choice C on the other hand, is saying that the passages disagree on whether the difference is fundamental, or whether there is an essential difference in the first place. A would agree with there being a qualitative difference (as lines 8-11, 27-29 show). B would disagree, and say there is only a difference in degree. (Lines 60-65)
