When light enters a new medium (like water), it bends due to refraction. This bending makes the fish appear at a shallower depth than it actually is. To compensate for this optical illusion, the archer should aim below the apparent position of the fish. Position 2 is the correct choice because it accounts for the light refraction, aiming directly at the fish's actual position rather than its apparent position above.
