The Himalayan rabbit's habitat has cold, snowy winters and mild summers. The body is typically covered in white fur except for the nose, feet, tail, and ears, which are covered in black fur.

Which of these best explains why the hair that grew back where the Ice pack was placed was black and not white?

a)

The white hair mutated to black hair as the rabbit's body temperature decreased.
