The distribution of melanin in the skin is primarily influenced by genetic factors, which determine an individual's natural skin tone and the potential for their body to produce melanin in response to UV radiation. Genetic differences among populations lead to variations in skin pigmentation, which have evolved as adaptive responses to varying levels of sunlight in different geographic areas.

While dietary habits and climate conditions can have indirect effects on skin pigmentation, they are not the primary drivers. For instance, certain nutrients may support skin health, and increased sun exposure in certain climates can lead to tanning, but these factors are secondary to the underlying genetic makeup that establishes baseline levels of melanin. Thus, understanding that genetic factors predominantly dictate melanin distribution clarifies why this option is the most accurate choice.
