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:

• A
  $M_Z = \frac{T}{C B}$
• B
  $M_Z = \frac{C B}{T}$
• C
  $C = \frac{M_Z B}{T}$
• D
  $C = \frac{T^2}{M_z B}$
