Solution
The correct option is D I, II and III
When a light ray falls on a non ideal surface, light ray undergoes three phenomena simultaneously. Some part of it gets reflected by the surface, some part of it gets absorbed by the surface and some part gets transmitted from the surface. The amount of light ray undergoing each of these phenomena varies depending on the surface.
For a polished surface, most of the light incident on it gets reflected.
For a transparent surface, most of the light ray passes through it.
For an opaque surface, most of the light ray incident on it gets absorbed by it.
