Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
The mass of the atom is mostly due to its nucleus. The nucleus contains neutrons and protons which have much than the weight of electrons combined together. According to Rutherford, Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
hence option B is the correct option.
