Answer 2

Answer:

Carbon monoxide

The solution in detail for carbon monoxide. Carbon monoxide, option A, is the proper answer. Car exhaust emits a poisonous gas called carbon monoxide.

Explanation:

• Motor vehicle emissions not only add to air pollution but also play a significant role in the development of smog in several major cities. Nearly a quarter of the hydrocarbons in our atmosphere, as well as more than half of the carbon monoxide, sulphur dioxide, and nitrogen oxide emissions, are caused by transportation.
• The gas known as carbon monoxide (CO) is colourless, odourless, poisonous, and non-irritating. It results from incomplete combustion of fuel, such as wood, coal, or natural gas. Carbon monoxide is mostly produced by motor vehicle exhaust.
