Human skin color is a polygenic trait, which means that multiple gene loci (with different alleles) are involved in its expression. It has been shown that there more than 350 genetic loci involved in determining skin color. Because of that, there is the enormous number of possible genotypes for the skin color and as a result, the phenotypes vary from the darkest brown to the lightest hues. Different populations have different allele frequencies of genes for human skin color, and the combination of these allele variations brings about complex and continuous variation in skin coloration. Natural skin color can change due to exposure to sunlight (becomes darker) and that is the way it adapts to intense sunlight irradiation (protection against the UV exposure).

Sounds like juan has a hard life. LOL CYANIDE CAPSULES?
A evolution of populations
I believe that the mystery organism is most likely a plant and not an alga if it is surrounded by a cuticle. Thus the answer is B.
Alga and plats are similar in that they can produce their won food from nutrients and sunlight by a process called photosynthesis. The main difference is in their complexity, such that algae are simple organisms, sometimes unicellular, and even the largest types are relatively simple in structure. Green algae does not contain cuticle.
