Solution
The correct option is D Carbon dioxide
Carbon dioxide can be used as a fire extinguisher. It is heavier than oxygen, so it forms a blanket and cuts off the oxygen supply. This extinguishes the fire.
Water is a good conductor of electricity. So, it cannot be used to extinguish electrical fires. Petrol is a fuel. Thus, it cannot be used for extinguishing fire. Oxygen is a supporter of combustion.
