Solution

The correct option is B Assertion and reason both are correct statements but reason is not correct explanation for assertion.
In Rutherford's experiment, only a few $α$ particles were deflected and most of them could pass through without any deviation. It is because most of the space inside the atom is empty.
Nucleus present inside the atom is heavy and the entire mass is concentrated in it.

So, Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
