Best answer
Correct Answer - b
As an alpha particle carries 2 units of positive charge, and a beta particle carries one unit of negative charge and `gamma` particle carries no charge , therefore electronic energy levels of the atom change for `alpha` and `beta` radioactivity , but not for `gamma`- radioactivity .
