Solution

The correct option is A

Non-inflammability


Fires can be extinguished by:

1. Cutting the supply of oxygen

2. Limiting the supply of fuel

3. Reducing the heat of surroundings

Being a non-inflammable material, when sand is dumped on a fire, it helps in cutting the supply of oxygen and absorbs a lot of heat.
