The light would become brighter as you approached the open door behind the wall because of refraction. The wall blocks the light source that's why it's dimmer at a distance. When the person approaches the light source, the visible light becomes brighter as the distance decreases.

Answer: B, diffraction

I might be wrong but I just took a test with this question and the majority of people put B.
