Air Pollution is defined as what?

Explanation:
Air pollution is the presence of harmful substances in the air from sources like industrial emissions, vehicle exhaust, and burning fossil fuels, which can lead to health problems. Those pollutants—such as fine particles and various gases—can irritate the lungs, worsen asthma, and increase the risk of heart and respiratory diseases, as well as affect the environment. The other options describe situations that aren’t about polluted air (absence of pollution, noise pollution, or an excess of clean air), so they don’t define air pollution.
