Answer

Brief Explanations:

The EVAP (Evaporative Emission Control) system is designed to prevent fuel vapors (hydrocarbons) from escaping into the atmosphere. A leak in this system would allow hydrocarbons to be released. Oxides of nitrogen ((NO_x)), exhaust gases (a broad term that includes multiple pollutants but not specifically what EVAP deals with), and carbon monoxide ((CO)) are not the primary substances that the EVAP system is meant to contain. The EVAP system's main focus is on hydrocarbon vapors from the fuel tank and fuel system.

Answer:

d. Hydrocarbons
