Rutherford's experiment which established the nuclear model of the atom used a beam of
(a) β-particles which inpringed on a metal foil and got adsorbed.
(b) γ-rays which impringed on a metal foil and ejected electrons.
(c) helium atoms, which impringed on a metal foil and got scattered.
(d) helium nuclei, which impringed on a metal foil and got scattered.
