At a particular point (in space and time) $\overrightarrow{\mathrm{E}}=9.6\ \hat{\mathrm{j}} \mathrm{V} / \mathrm{m}$. The value of magnetic field at this point is:
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 $\tan ^{-1}\left(\mu_{ g }\right)$ 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 :
