Answer 2

B. it is lighter than air

Explanation:

Carbon dioxide is heavier than air and will tend to blanket the fire. The CO2 inside the fire extinguisher is in liquid form. When it is sprayed on a fire, it turns into powdered dry ice which is -109 degrees Farenheit or -78 C. Carbon dioxide does not conduct electricity, so these fire extinguishers can be used for electrical fires as well.

Option B is the answer.
