C. The refractive index of water with respect to refractive index of air is the ratio of the speed of light in air to that in water — The correct choice is The refractive index of water with respect to refractive index of air is the ratio of the speed of light in air to that in water. It follows from the laws of reflection/refraction and the standard image-formation properties of lenses, mirrors or optical systems.
