Hint Reflected light is what we see, when we look at an object exposed to light. When light is incident on a surface, some are transmitted through the surface or absorbed while some are “rejected” to be seen by the eye.

Complete step by step answer
When a direct light (light directly coming from a luminous object without much interaction with its surrounding) strikes a surface, it is either allowed to go through the surface or it is rejected by the surface. The rays which are allowed to pass through are called transmitted ray (or light). This transmitted ray for most substances, soon gets absorbed by the molecules of the material and acts to increase the temperature of the material. This is why an object exposed to light gets hot soon enough. However, for some substances, the transmitted light goes completely through the entire width of the substance, and emerges from the other end of the material. These substances are said to be transparent, and are called transparent materials.
On the other hand, the rejected lights are scattered about (for most substances) onto other surfaces (of which it may also be reflected or transmitted) or into the eyes. These rejected light are said to be reflected from the surface, thus are called reflected rays.
Hence, reflected ray is, indeed, the ray of light reflected from a surface.
Thus, the correct option is A.

Note
In actuality, reflection is a solid phenomenon, i.e. it actually takes place within the solid and not the surface of the solid. In fact, which wavelength of light gets reflected is determined by the arrangement of the molecules, the width of the topmost molecules from the next ones, etc. However, reflection is often determined from the first few molecules, and are thus approximated as a surface phenomenon.
