Solution

The correct option is D
ANSWER:
The susceptibility of a paramagnetic substance is +ve and independent of the magnetising field.

Hence the correct option is (A).

Additional information :

The susceptibility of a paramagnetic substance depends on temperature as

$X_{m} \propto \frac{1}{T}$

(T= absolute temperature).
