Answer :
Final answer:
When a leak occurs in the EVAP system, hydrocarbons, which are fuel vapors, are released into the atmosphere. The EVAP system is essential for preventing air pollution from fuel emissions. Thus, the correct answer is hydrocarbons.
Explanation:
Understanding EVAP System Leaks
The EVAP (Evaporative Emission Control) system in vehicles is designed to prevent the release of fuel vapors into the atmosphere, thereby reducing air pollution. When there is a leak in the EVAP system, it primarily allows fuel vapors, which are composed of hydrocarbons, to escape into the atmosphere.
This is because hydrocarbons are a major component of gasoline and are regulated due to their negative impact on air quality and their role in forming ground-level ozone. In contrast, options such as oxides of nitrogen or carbon monoxide are typically associated with combustion processes and exhaust emissions, not specifically with the EVAP system. Therefore, the correct answer to the question is:
- d. Hydrocarbons
