Correct answer only !

which shows the correct reflected ray?

The answer would be:

D.

Here's why:

According to the Law of Reflection, in a smooth the angle of incidence should be equal to the angle of reflection. This means that the angle of incidence of the ray from the normal, will create a reflected ray that measures the same as ray of incidence from the normal.

It is confusing, but look that the image below to grasp the explanation.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
