Which system controls emergency exits on a school bus?

Answer: C — Emergency exit control system

The system that controls emergency exits on a school bus is the emergency exit control system. This specialized system is designed to ensure that emergency exits can be quickly and easily operated in the event of an emergency, allowing for the swift evacuation of passengers. It typically includes mechanisms like push-out windows or exit doors and may be integrated with warning signals to indicate that an exit is in use. The ignition system primarily controls the engine's operation and does not play a role in managing emergency exits. The electrical control system encompasses a broader range of electrical components in the bus, such as lighting and entertainment systems, but it doesn't specifically focus on emergency exits. The navigation system is involved in guiding the bus along its route and does not interact with the safety features related to passenger exits. Thus, the emergency exit control system is the dedicated component that ensures safe egress from the bus when needed.
