Solution

The correct option is B $M_{z} = \frac{C B}{T}$
According to Curie's law:-

$X \propto \frac{1}{T}$ , where $X$ =magnetic susceptibility and $T =$ temperature

$⟹ X = \frac{C}{T}$ , where $C$ =Curie's constant

Magnetization, $M_{z} = X B$

$⟹ M_{z} = \frac{C B}{T}$

Hence, answer is option-(B).
