Light traveling at some angle as it moves from water into the air is refracted away from the normal as it enters the air, so the fish you see underwater is actually to the water surface than it appears.

a) closer
b) farther
c) at the same distance

a) closer

Explanation:

Refraction causes illusion of optics. For example, if you put your feet in the water, they will appear to be greater than they are.

With a fish, they will appear to be closer to the water surface, due to the angle between the human eye and the water surface.

So the correct answer is:

a) closer
