A Correct answer
Explanation

Darker skin has more melanin, which provides protection against harmful ultraviolet radiation. Tropical regions near the equator receive the most intense and direct UV radiation year-round. Evolution has favored darker skin pigmentation in these regions as an adaptive protection, while lighter skin evolved in areas with less UV exposure.
