Explanation:

Arctic animals have adaptations like fur and a fat - layer to insulate against cold. Burrowing is not a common way to stay alive for most Arctic animals. Special foods are not the main factor for staying warm. While some may migrate, having fur and fat is a more general adaptation for survival in the cold Arctic.

C. They have fur and a layer of fat that keeps them warm.
