Answer 1

The correct option is: (b)

Explanation:

Cold blooded animals have no fat layer. The skin of cold-blooded animal is devoid of any fat layer because temperature regulation-the important function of fat layer, is not necessary here. But fat bodies are present in front of each testis. They are reserves of nourishment and coldblooded animals may use them in hibernation.
