Answer 1

The correct response is:

Humans exposed to less UV light required less melanin to make more vitamin D for healthier bones.

This explanation reflects the understanding that variations in skin pigment are influenced by the amount of ultraviolet (UV) light in different geographical regions. In areas farther from the equator, where UV light is less intense, lighter skin may be advantageous for the synthesis of vitamin D.
