The correct option is B nucleus
Rutherford's atomic model also known as a nuclear atom. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the centre of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom.
