A
$$\sin ^{-1}\left(\tan r^{\prime}\right)$$
B
$$\sin ^{-1}(\tan r)$$
C
$$\tan ^{-1}(\sin \mathrm{i})$$

The angle of prism is $$A$$ and one of its refracting surface is silvered. Light rays falling at an angle of incidence '$$2 \mathrm{A}$$' on the first surface return back through the same path after suffering reflection at the silvered surface. The refractive index of the material of the prism is

A
$$2 \sin \left(\frac{\mathrm{A}}{2}\right)$$
B
$$2 \tan \mathrm{A}$$
C
$$2 \cos \mathrm{A}$$
D
$$2 \sin \mathrm{A}$$
