Solution

The correct option is C $1.13$
Given:
Refractive index of rock salt with respect to air, $n_{r} = 1.54$
Refractive index of alcohol with respect to air, $n_{a} = 1.36$
Therefore, refractive index of rock salt with respect to alcohol, $n_{r a} = \frac{n_{r}}{n_{a}} = \frac{1.54}{1.36} = 1.13$
