Best answer
Right option is (a) Diamagnetism

The best explanation: Diamagnetism is caused due to the modifications of motion of electrons which produces an opposing magnetic field. The magnetic lines of force are repelled, which results in weak force and low susceptibility. Copper, mercury, and gold are common examples of diamagnetic materials.
