When the atoms of gold sheet are bombarded with a beam of -particles, only a few a-particles get deflected where as most of them go straight undeflected. This is because
(A) The force of attraction on the -particles by the oppositely charged electron is not sufficient
(B) The nucleus occupies much smaller volume as compared to the volume of atom
(C) The force of repulsion on fast moving -particles is very small.
(D) The neutrons in the nucleus do not have any effect on -particles
