In a species of lily, the color of the flower’s petals is determined by a dominant purple allele (F) or recessive white allele (f). One hundred flowers in Hardy-Weinberg equilibrium were sampled, and only 15% of the population showed the phenotype of white.

Which of the following numbers represents the calculated value of the recessive white allele frequency?

A - 0.92

B - 0.39

C - 0.15

D - 0.85
