Answer 2

Explanation:

Water and sand is used to extinguish fires because when we throw it on a fire, it prevents the fire from coming in contact with oxygen. as we know that oxygen is needed for the burning, the water and sand extinguishes the fire as the fire does not get enough oxygen for burning.
