Correct option is
A

True

The blanket do not insulate; actually air insulates.
Air is trapped in the space between two thin blankets. Since air is insulator of heat, it prevents the escape of body heat. The air can't pass deeper and the layers will stop the air in two thin blankets where as there are no layers and air can pass deeper in one thick blanket. That's why two thin blankets are usually warmer than one thick blanket.
