The correct option is A Small and negative Diamagnetic materials create an induced magnetic field in a direction opposite to an external applied magnetic field and are repelled by applied magnetic field.
Magnetic permeability of the diamagnetic materials is little less than unity.
Thus magnetic susceptibility of diamagnetic materials is very small and negative.
For example : For Silicon,χm=−4.2×10−6
