Which of the following is a common air pollutant associated with industrial activities?

Industrial activities often release a variety of pollutants into the atmosphere, and ozone, carbon monoxide, and nitrogen dioxide are all commonly associated with these emissions.

Ozone is a secondary pollutant formed from the reaction of sunlight with other pollutants, primarily from industrial processes and vehicle emissions, making it a significant concern in urban air quality.

Carbon monoxide is produced during the incomplete combustion of fossil fuels, which is prevalent in industrial settings. High levels of this gas can pose serious health risks.

Nitrogen dioxide is a byproduct of combustion processes, particularly in power plants and industrial boilers. It contributes to the formation of smog and acid rain, making it a critical air quality issue.

Since all three pollutants are linked to industrial activities, they collaboratively highlight the environmental impact of such operations, leading to the conclusion that the correct answer encompasses all of them.
