Answer:

D)

Explanation:

Color is determined by a sex-linked gene, X gene, so, in order to that, the gene is maternally inherited.   When one gene is related to the X chromosome, and one of the alleles is recesive and the other, logically dominant, the first generation will be of a single color, and the second generation will be of the other single color.
