Quizplus · Accepted Answer

While ozone does naturally form in the stratosphere and serves to protect Earth from harmful UV radiation, it is considered a pollutant when produced near the surface through chemical reactions involving nitrogen oxides and volatile organic compounds. Ground-level ozone can cause respiratory problems and damage to crops and vegetation. Smog (A), nitric acid (C), and sulfur dioxide (D) are also air pollutants, but they do not naturally occur in the stratosphere.
