Solution

The correct options are
B J.J. Thomson
C Niels Bohr
D John Dalton
Maharishi Kannad postulated that every matter can be broken down and reaches a stage where it can't be broken down further but never proposed a model to describe the working and properties of an atom.

John Dalton has proposed one of the earliest atomic model where he said that atoms are indivisible, indestructible and can combine and rearrange themselves.

J. J. Thomson discovered electrons and proposed an atomic model composed of charged particles.

Niels Bohr put forward the model of atom with fixed orbits in which electrons revolve around the nucleus.
