B Correct answer
Explanation

Light refraction occurs because light travels at different speeds in different media. When light passes from one medium to another (like air to water), the change in speed causes the light to bend at the interface between the two media. This bending phenomenon is what we call refraction. Option A describes the effect but not the cause, option C is incorrect as refraction involves bending, and option D doesn't explain why refraction happens.
