Answer:
D) the white fur helps them camouflage against predators
Explanation:
The best explanation for why their fur turns white in winter is that the white fur helps them camouflage against predators. While the white fur is beautiful, it actually reflects more sunlight than a darker coat so it does not absorb warmth or conserve energy. And because it helps them blend into their environment, not only will it aid in it being preyed upon, but it also may hinder their ability to find a mate.
