Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Cold blooded animals are the ones that change according to the surrounding environment and cannot maintain constant body temperature. They do not have a fat layer under the skin. In extreme winter condition, cold-blooded animals undergo hibernation where all the body processes are slow down and it is a kind of dormancy. Here the stored fat layer is used to provide food to the animal and thus there is no stored fat layer.
So, the correct option is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'
