Whose model can also be called the nuclear model of the atom?

The correct answer is Option (2) → Rutherford

Rutherford explained the α-particle scattering results with a new picture of the atom. In it, the entire positive charge and most of the mass sit in a tiny central nucleus. The electrons revolve round it like planets round the sun. So his planetary model is also called the nuclear model of the atom.

NCERT (2026-27):
Introduction – “… The explanation of the results led to the birth of Rutherford’s planetary model of atom (also called the nuclear model of the atom). According to this the entire positive charge and most of the mass of the atom is concentrated in a small volume called the nucleus with electrons revolving around the nucleus just as planets revolve around the sun.”
