In guinea pigs, the allele for black coat color (B) is dominant over the allele for white coat color (b). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 31 guinea pigs, 2 are homozygous dominant, 11 are heterozygous, and 18 are homozygous recessive.

What is the frequency of the recessive allele in the population? Show all work.
A. 0.88

B. 0.12

C. 0.76

D. 0.64
