Refracted light rays ...

A - are bent as they pass into a different medium

B - are absorbed by an object

C - are reflected from an object at a variety of angles

D - bounce off a medium

A.

Explanation:

Refraction light rays are bent as they pass into a different medium where its speed is different. As refracted light rays pass from a fast medium to a slow medium, the light ray bends toward the normal to the boundary between the two medium. Light refracts as it travels at an angle into a medium with a different refractive index.
