Answer

Brief Explanations:

The Exhaust Gas Recirculation (EGR) system works by taking some of the exhaust gases (which are already burned) and re - introducing them into the intake system. This helps in reducing the formation of oxides of nitrogen ((NO_x)) by lowering the combustion temperature. The fuel system is for delivering fuel to the engine, the converter (like a catalytic converter) is for treating exhaust gases further, and the operating system is a very general term. The EGR valve specifically directs the exhaust gases to the intake system.

Answer:

B. Intake
