Given below are two statements : Statement I : If the Brewster's angle for the light propagating from air to glass is $\theta_{\mathrm{B}}$, then Brewster's angle for the light propagating from glass to air is $\frac{\pi}{2}-\theta_{\mathrm{B}}$. Statement $U_i$ : The Brewster's angle for the light propagating from glass to air is $\tan ^{-1}\left(\mu_g\right)$ 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.
