The answer is D. This is Rutherford’s experiment where he wanted to prove the existence of a nucleus in an atom. Ernest Rutherford along with his students Ernest Marsden and Hans Geiger bombarded alpha particles into a very thin gold foil and had an observation that 1/8000 of the particles deflated at a large angle.

They observed it under a microscope on a screen of zinc sulfide in the dark. It was then they confirmed that strong electric fields exist. He then concluded that a positive-charged atom lies in a compact and solid nucleus. This nucleus concentrates almost the whole mass of the atom but occupies only hundred millionth of a millionth of the atom’s volume.

Unoccupied space

Because most of the particles do not hit anything and pass right through the gold foil, one can infer that the atom is mostly just empty space.
