The correct answer is: A. CO
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced when gasoline is burned in an engine. It is a major pollutant in automobile exhaust and can be harmful to human health.
Carbon monoxide binds
to hemoglobin in the blood, preventing it from carrying oxygen to the body’s tissues. This can lead to a variety of health problems, including headache, dizziness, nausea, and vomiting. In severe cases, carbon monoxide poisoning can be fatal.There are a number of ways to reduce carbon monoxide emissions from automobiles. One way is to use catalytic converters, which convert carbon monoxide into carbon dioxide and water. Another way is to tune engines properly so that they do not produce excessive amounts of carbon monoxide.
Carbon dioxide (CO2) is a colorless, odorless, and tasteless gas that is produced when gasoline is burned in an engine. It is a greenhouse gas that contributes to climate change.
Nitrogen oxides (NOx) are a group of gases that are produced when gasoline is burned in an engine. They can cause smog and acid rain.
Hydrocarbons are a group of compounds that are made up of hydrogen and carbon. They are produced when gasoline is burned in an engine. Some hydrocarbons can contribute to smog.
In conclusion, the main product of automobile exhaust is carbon monoxide (CO).
