Answer:

C) Reflection

Explanation:

-Diffraction: is the spreading of waves when they go around an object. It happens for example in X-rays.

- Interference: is when the waves meet and the distribution of energy of one wave is affected by the other. Interference can be seen in radio waves.

-Reflection is when the light falls in the surface of something and is sent back. An example are the CD's and DVD's.

-Refraction is when a wave changes direction when going from a medium to the other because of a variation in the speed. An application are the glasses.

According to this, the property of light that is used in CD's and DVD'S is reflection.
