Option C: Natural selection favored alleles for light skin in Europe.

The theory of Natural Selection was firstly expounded by Charles Darwin. It is a key mechanism of evaluation, the change in the heritable traits, and characteristic of a population over a generation.

Natural selection favored alleles for light color skin in Europe because of the well-known correlation between skin pigmentation and distance from the equator. Relethford strongly suggests that natural selection in response to environmental factors plays an important role in the geospatial patterning of human skin pigmentation variation. The lighter level of UVR required to synthesize vitamin D, which is higher in individuals with dark color skin means the region near the equator. The European region does not receive much UVR that's why in Europe alleles of light skin are favored.
