Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Air is trapped in the space between two thin blankets. Since air is an insulator of heat, i.e., a bad conductor of heat, it prevents the escape of body heat. So two thin blankets put together are warmer than a single blanket of double the thickness.
