Which statement best explains the height-based role of ozone?
Answer and explanation
Correct answer: It is protective in the stratosphere and can be a pollutant in the lower troposphere
The governing concept is that the environmental effect of ozone depends on its altitude and concentration. In the stratosphere, the ozone layer absorbs harmful ultraviolet radiation and protects life. Near the ground in the lower troposphere, ozone is a secondary pollutant produced through sunlight-driven reactions involving nitrogen oxides and volatile organic compounds; it can damage lungs and plants. Therefore C is correct, while A reverses the useful and harmful contexts and B and D are false.
