In the mythical frost-fox (Vulpes glacialis), sex is determined by XX/XY chromosomes, and sapphire eye glow is an X-linked recessive trait ($X^b$), whereas standard amber glow is dominant ($X^B$). A researcher crosses an amber-eyed female whose father had sapphire eyes with a sapphire-eyed male. If this pair produces a male kit, what is the probability that this kit will display sapphire eye glow, along with his corresponding genotype?

A) 100% probability, with the genotype $X^b Y$

B) 25% probability, with the genotype $X^b X^b$

C) 0% probability, with the genotype $X^B Y$

D) 50% probability, with the genotype $X^b Y$
