Answer & Explanation
The correct answer is Option C: Supply and exhaust ventilation.
Activating a fixed CO2 system is designed to extinguish fires by displacing oxygen. To prevent re-ignition and potential damage, it automatically shuts down ventilation fans that could supply air to the fire or spread the gas. Engine propulsion and power distribution are typically handled manually or through other safety interlocks.
