Why is ozone called a pollutant in the lower troposphere and a protector in the stratosphere?
Answer and explanation
Correct answer: Its effect changes with location
Option A is correct because ozone’s effect depends on where it occurs. In the lower troposphere, ozone is a reactive secondary pollutant formed from nitrogen oxides and volatile organic compounds in sunlight; it can irritate lungs and damage plants. In the stratosphere, ozone absorbs harmful ultraviolet radiation, helping protect living organisms. The molecule is the same, but its location and role differ.
