The answer to this question is D which is all of A, B, and C. Take note that there are always differences depending on the surface wherein the light would hit. If it would hit a translucent object, only some of the light may be reflected as translucent objects allow some light to pass through. This means that only a few rays of light will be reflected. When the light hits an opaque object, that is the time when all of the light may be reflected.

A is the one constant thing. The light will refract away from the normal. Take note that there will also be differences depending on the matter that will be hit. It will be different for solids, liquids, and gases.
