Why does a para magnetic sample display greater magnetization (for the same magnetizing field) when colled ?

Question

$\begin{array}{1 1} \text{The random thermal motion of atom increased } \\ \text{The random thermal motion of atom decreased } \\ \text{The random thermal motion of atom is equal to the magnetic field} \\ \text{The magnetic field is less than the random thermal motion of atom } \end{array}$
