AI Explanation
The correct answer is D) All the above. Isoprene is a flammable hydrocarbon that can be effectively extinguished using foam, dry chemicals, or CO2 as extinguishing agents. All three of these agents are effective in combating an isoprene fire because they work by smothering the fire, interrupting the chemical reaction, or displacing the oxygen necessary for combustion. The US Coast Guard regulations recognize these three extinguishing agents as suitable for fighting fires involving flammable liquids like isoprene.
