What would most likely be the gene combinations of three brown-eyed children of parents that both carry a dominant and recessive gene for brown eye color?

Let B represent the dominant brown-eye allele and b the recessive allele. Two parents who each carry both alleles have the genotype Bb, so their children can be BB, Bb, or bb. Since all three children are described as brown-eyed, none can be bb; choice D, BB, Bb, and BB, contains only brown-eyed genotypes.
