Hint: Magnetic
susceptibility is a proportionality constant that determines the degree of
magnetization of a material with respect to the applied magnetic field.
Solution:
Step1: The magnetic susceptibility denotes
whether a material is repelled out or attracted of a magnetic field. It is
negative only for diamagnetic material and it is positive for paramagnetic
material and ferromagnetic material has large positive magnetic susceptibility.
Hence option ‘A’ is correct.
