Verified by Toppr

Most of the space in the atom is empty and only 1 in 20,000 of alpha particles are deflected in Rutherford's experiment.
Very small no. of alpha particles are deflected by the positively charged nucleus as the size of the nucleus is very small.

Hence, option (B) is the correct answer.
