What is the system responsible for carrying harmful fumes from the engine?

The exhaust system is the correct answer because it is specifically designed to carry harmful fumes and gases away from the engine and out of the vehicle. This system plays a crucial role in reducing the emission of pollutants, thereby minimizing their impact on the environment and ensuring that the air inside the vehicle cabin remains clean and safe for passengers.

The exhaust system includes components such as the exhaust manifold, catalytic converter, muffler, and exhaust pipes, which work collectively to direct the exhaust gases produced during combustion away from the engine and out of the vehicle. The catalytic converter also plays an important role in converting harmful substances in the exhaust into less harmful emissions before they are discharged into the atmosphere.

In contrast, the ignition system is responsible for starting the engine by creating a spark to ignite the fuel-air mixture, the fuel system delivers fuel to the engine for combustion, and the suspension system supports the vehicle body and provides a smooth ride. None of these systems are tasked with managing exhaust gases, which solidifies the exhaust system as the answer to the question regarding the carrying of harmful fumes.
