When a gold sheet is bombarded by a beam of \( \alpha \) -
P particles, only a few of them get deflected whereas

W most go straight, undeflected. This is because
(A) The force of attraction exerted on the \( \alpha \) particle by the oppositely charged electrons is not sufficient.
(B) A nucleus has a much smaller volume than that of atom
(C) The force of repulsion acting on the fast moving \( \alpha \)-particles is very small.
(D) The neutrons in the nucleus do not have any effect on the \( \alpha \)-particles
