C

Skin color is largely determined by the number of melanocytes in a persons skin, which produce melanin--increased melanin means darker skin. Melanin protects skin from the ultraviolet rays of the sun, so sun exposure causes melanocytes to increase melanin production. Albinism occurs when the skin fails to produce melanin.
