Answer & Explanation
The correct answer is Option B: At the base of the flames.
The discharge from a carbon dioxide fire extinguisher should always be directed at the base of the flames. This is where the fuel is being vaporized and combustion is occurring, allowing CO2 to displace oxygen and cool the fuel.
