What harmful components are found in snowmobile exhaust?

The presence of CO2, hydrocarbons, and nitrogen oxides in snowmobile exhaust is significant due to their environmental and health impacts. Carbon dioxide (CO2) is a greenhouse gas that contributes to climate change. Hydrocarbons are unburned fuel particles that can lead to ozone formation when they react with sunlight, causing smog and respiratory problems. Nitrogen oxides (NOx) also play a role in creating ground-level ozone and can lead to the formation of fine particulate matter, which poses health risks.

These components illustrate the harmful effects of pollution generated by snowmobiles, highlighting the importance of understanding and managing emissions for both environmental protection and public health. The combination of these gases makes option B correct, as it accurately reflects the harmful components found in snowmobile exhaust.
