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.

A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice pack over the shaved area. The shaved area grew black fur. Which of these best explains why the hair that grew back where the ice pack was placed was black and not white?

• The coat color changed from white to black with the age of the rabbit.

• The genes for black hair were activated by specific temperatures.

• White hair only grows during certain times of the year.

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