Solution

The correct option is B
Very dark and very fair

Considering $\frac{A}{a}, \frac{B}{b} a n d \frac{C}{c}$ as the three genes responsible for skin color inheritance, the dominant alleles A, B and C represent greater melanin production and the recessive alleles a, b and c represent less melanin production. Thus, a person with the genotype AABBCC would be very dark, while a person with the genotype aabbcc would be very fair.
