Solution

The correct answer is D) I and III only.

Explanation:

I. Water is indeed a good fire extinguisher for certain types of fires, such as those involving wood, because it can cool the fuel below its ignition temperature.

II. However, water is not a good fire extinguisher for burning oils and electrical equipment. Water can cause oil fires to spread, and it can conduct electricity, which can lead to electrocution.

III. Sand and soil can act as good fire extinguishers for burning oils because they can smother the fire, cutting off its oxygen supply.
