If $M_z$ is the magnetization of a paramagnetic sample,$B$ is the external magnetic field,$T$ is the absolute temperature,and $C$ is the Curie constant,then according to Curie's law in magnetism,the correct relation is:

Given below are two statements:
Statement-$I$: Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature.
Statement-$II$: Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field.
