Statement I- Thomson's atomic model could not explain the result of scattering experiment performed by Rutherford.
Statement II- According to Rutherford, majority of mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons.

The correct option is B Both the statements are correct.
According to Thomson's atomic model, the positive charge is uniformly distributed in the sphere and electrons are embedded in it just like a plum pudding.This implies that when alpha particles are bombarded on the atoms, they should get deflected uniformly.
However, in the Rutherford alpha particle scattering experiment, it was found that rays were deflected in various angles.
