Answer:

Option C:

CO2 can displace oxygen around the flame because it has a higher density than air.

Explanation:

CO2 is heavier - or in this case, we can say denser than air.  In addition to that, CO2 does not support burning. t is a major component in fire extinguishers that are designed to stop minor domestic fire incidents.

Since CO2 is denser than air, it sinks to the bottom of the room, and surrounds the flame with an atmoshphere inert to combustion, pushing the oxygen upwards in the process, away from the reach of the flames.

This causes the fire to starve to death from lack of oxygen
