The correct options are
A Water
B Mud
C Fire extinguisher
Fuel and air are the two main ingredients for a fire.
To control the fire, we have to cut supply of one of the ingredients.
Water, mud and fire extinguisher acts as a blanket on the fuel. They don't allow air to come in contact with fuel. Thus, fire is controlled.
On the other hand, paper is inflammable substance, that cannot control fire.
