Which system manages exhaust emissions in a school bus?

Answer: C — The emissions control system, including the catalytic converter

The emissions control system is specifically designed to manage and reduce harmful exhaust emissions produced by the engine. This system includes components like the catalytic converter, which plays a critical role in converting harmful pollutants in exhaust gas into less harmful emissions before they are released into the atmosphere. By facilitating chemical reactions that reduce nitrogen oxides, carbon monoxide, and unburned hydrocarbons, the emissions control system helps ensure that school buses meet environmental regulations and contribute to cleaner air quality. The other options, while important in their respective functions, do not directly address exhaust emissions. The fuel injection system is responsible for delivering the proper amount of fuel to the engine, the suspension system supports vehicle stability and comfort, and the air conditioning system manages cabin temperature and comfort. None of these systems are designed to specifically manage or reduce the emissions from the exhaust.
