B Correct answer
Explanation

Ultraviolet (UV) radiation from the sun penetrates the skin and damages DNA, causing sunburn and increasing skin cancer risk. UVB rays are primarily responsible for sunburn, while UVA rays contribute to skin aging. Infrared radiation heats the skin but doesn't cause sunburn, and visible light doesn't damage skin in this way.
