Solution

The correct option is B $μ_{A} = μ_{C} < μ_{D} < μ_{B}$
If ray bends towards the normal then the medium is optically denser than the medium of incidence hence we can observe
$μ_{B} > μ_{A}; μ_{B} > μ_{C}; μ_{A} = μ_{C}$
$μ_{C} < μ_{D} a n d μ_{B} > μ_{D}$
hence
$μ_{A} = μ_{C} < μ_{D} < μ_{B}$
