Solution

The correct option is D Absorbs harmful radiation
Melanin is responsible for skin colouration and is an effective absorber of light. It is able to dissipate over 99.9% of absorbed UV radiation. This is the reason why lighter skinned people have more chances of suffering from skin cancer when compared to people with darker skin.
