Yosef Ballard · Answer 1

You have two answers that are pretty close. He mentioned D, but what he really found and stuck with it and concentrated on it when submitting his findings was that the nucleus of an atom was small and concentrated at the center of the atom.

So the answer is C but you cannot easily eliminate D. I think the question is somewhat faulty, but C should give you the mark.
