Solution

The correct option is C Assertion is correct but Reason is incorrect
If the refractive index of two medium is same then light wave will travel in a straight line without bending.
According to Snell's law $n_{1} s i n θ_{1} = n_{2} s i n θ_{2}$
$n_{1} = n_{2}$ $⟹ θ_{1} = θ_{2}$
So we can see that the bending of light will depend upon the refractive index of medium.
