The statement, which matches the scientists to their research in atomic theory is this: RUTHERFORD USED GOLD FOIL, THOMSON DISCOVERED ELECTRON. THUS THE CORRECT OPTION IS C.
Rutherford gold foil experiment was a landmark atomic experiment, which prove that every atom has a positive center that is called nucleus. With this experiment, Ernest Rutherford was able to establish the atomic nuclear theory.
J.J. Thomson was the scientist, who discovered the electron in 1897, when he was experimenting with the cathode ray. He was able to demonstrate that cathode ray was made up of negatively charged particles, which he called electrons.
