Best answer
Correct option is (a) Dia-magnetic material

The explanation is: In a diamagnetic material, the electron orbits are more or less random, and mostly all the magnetic moments are cancelled. Similarly, all the spins are almost paired. Hence the net magnetic moment in the diamagnetic material is zero.
