(A) Color blindness is an $X$-linked recessive trait. For a girl to be color-blind,she must inherit the recessive allele $(X^c)$ from both parents. This means her father must be color-blind $(X^cY)$ and her mother must be either a carrier $(X^CX^c)$ or color-blind $(X^cX^c)$. Since the question implies the rarity of the condition,the most specific scenario is that the father is color-blind and the mother is at least a carrier. However,looking at the provided options,the condition where a girl is color-blind requires the father to be color-blind and the mother to carry the gene. Option $A$ is the most accurate description of the genetic requirement.
