Which of the following properties is responsible for the bending of light when it moves from air into water?
Change in speed of light
Light bends when moving from air into water due to a change in its speed as it crosses into a denser medium, a phenomenon called refraction.
Gravity, temperature change, and colour change are not the actual cause of this bending — the speed change of light is the underlying physical reason.
Hence, 'Change in speed of light' is the correct answer.
