Option (b).

Explanation:

Genes may be defined as the functional segment of DNA that are heritable in nature. Genes are responsible for the genotype and phenotype of the living organisms.

The eye color in case of humans is the example of polygenic inheritance. The eye color is controlled by more than two different genes and not just by the two alleles of a particular gene. The presence of the different alleles in the different individuals determine the eye color.

Thus, the correct answer is option (b).
