Magnetic susceptibility for a paramagnetic and diamagnetic material is respectively

The universal property of all substances is

Given below are two statements:
Statement $I$: The diamagnetic property depends on temperature.
Statement $II$: The induced magnetic dipole moment in a diamagnetic sample is always opposite to the magnetizing field.
In the light of the given statements,choose the correct answer from the options given below:

$A$ susceptibility of a certain magnetic material is $ 400 $. What is the class of the magnetic material $ ? $

$A$ paramagnetic substance is placed in a non-uniform magnetic field, then

For two types of magnetic materials $A$ and $B$, the variation of $\frac{1}{\chi}$ ($\chi$: magnetic susceptibility) versus temperature $T$ is shown in the figure. Then:
