Given below are two statements:
Statement $I$: If the Brewster's angle for the light propagating from air to glass is $\theta_B$,then Brewster's angle for the light propagating from glass to air is $\frac{\pi}{2} - \theta_B$.
Statement $II$: The Brewster's angle for the light propagating from glass to air is $\tan^{-1}(\mu_g)$ where $\mu_g$ is the refractive index of glass.
In the light of the above statements,choose the correct answer from the options given below:

• A
  Statement $I$ is true but Statement $II$ is false.
• B
  Both Statement $I$ and Statement $II$ are true.
• C
  Both Statement $I$ and Statement $II$ are false.
• D
  Statement $I$ is false but Statement $II$ is true.
