Solution

The correct option is B CO2
In case of fires that involve electrical equipment and inflammable materials, carbon dioxide (CO2) is used as extinguisher. It is heavier than oxygen and covers the fire like a blanket. This way, the contact between the fuel and oxygen is cut off, and the fire is controlled. Moreover, carbon dioxide does not harm the electrical equipment.
