The explanation of the incorrect options:
A) Rutherford: Rutherford suggested the solar system model in which the nucleus is present at the centre and the electrons revolve around it in circular orbits similar to the way planets revolve around the sun. The electrons spin as they move around the nucleus.
B) Democritus: Democritus told that atoms were uniform, solid, hard, incompressible and indestructible and that they moved in infinite numbers through empty space until stopped.
