• C. It limits the supply of oxygen and it smothers the fire.
• D. Sand is flammable.

Answer 1

The correct option is C

It limits the supply of oxygen and it smothers the fire.

Soil that is free of flammable organic materials is helpful in extinguishing fires. Soil works like other extinguishing materials by absorbing heat and suffocating the fire by cutting down the oxygen supply. Soil is best used on small outdoor fires and cooking fires that are slow burning. It may need to be combined with water and spread around to smother flames and ashes.
