Which involves reflection of light waves?

a) a full moon shows sunlight bouncing off the moon's surface and traveling toward earth.

b) ultraviolet waves of energy are taken in by sunburned skin.

c) a black car will heat up more in the sun than a lighter colored car.

A) A full moon shows sunlight bouncing off the moon's surface and traveling toward Earth.

I say this becasue, the reflection of the light waves is the sun being reflected off of the moon. The moon isn't shinning, it's just the sun's like off of the moon that was see. Thus, it travels to the earth in that matter. 

Hope this helps.
