Solution
The correct option is C Fur
An important characteristic of mammals is that they are warm-blooded; they need a high body temperature to survive. Hair and fur trap air, creating a layer that insulates the skin on their bodies from the environment's colder temperatures. The thicker the fur, the warmer the body will be.
