Skin cancer is more common among​

A) ​dark-skinned people.
B) ​light-skinned people.
C) ​light-skinned people who avoid the sun.
D) ​people in Europe rather than people in the United States.

Skin cancer is more common among light-skinned people because they have less melanin, which is the pigment that protects the skin from the sun's harmful UV rays. Dark-skinned people have more melanin, which provides a natural protection against sun damage. Avoiding the sun can reduce the risk of skin cancer, but light-skinned people are still at a higher risk even if they stay out of the sun. There is no evidence to suggest that skin cancer is more common in Europe compared to the United States.
