GMAT Sentence Correction (SC) | Re: The ability of neuroscientists

C is not a good answer, although I agree that we can eliminate the rest, too. However, be careful about eliminating choices because they seem a bit awkward or because they differ from the "original." There really is no original! Treat answer choice A just like all the others, as one of five possible answers. We don't need to justify every change of wording between A and the other choices.
