Correct choice is (a) False

Easiest explanation: Coulomb’s Law is not valid for inter-atomic distance i.e. distance less than 10^-15 m. Besides, if the distance between the two bodies is less than the size of any of the bodies, this law is also invalid. We can use this law only in all other cases.
