Solution

The correct option is C

Blanket cuts off the supply of oxygen which in turn stops combustion.


The essential requirements for producing fire are fuel, air (to supply oxygen), and heat. Fire can be controlled by removing one or more of these requirements. As oxygen gas is essential for combustion, by putting a blanket around the person, the supply of oxygen is cut down. So, it stops the combustion and the person can be saved.
