The correct answer is A) Ultraviolet radiation.

Melanin is a pigment produced by melanocytes in the skin, hair, and eyes. Its primary function is to absorb harmful ultraviolet (UV) radiation from sunlight, thereby protecting the cells from DNA damage and reducing the risk of skin cancer.

The amount and type of melanin produced influence skin, hair, and eye color. More melanin provides greater protection against UV radiation. While skin provides some protection against other forms of radiation, melanin’s specific role as a pigment is most directly linked to absorption of UV radiation.
