- A. PAN
- B. CO2
- C. Ozone
- D. NO2
Explanation
Summer smog, or photochemical smog, is a complex mixture of pollutants. The primary component and indicator of this type of smog is ground-level ozone (O3), which is formed by chemical reactions between oxides of nitrogen and volatile organic compounds in the presence of sunlight.

About Environmental Chemistry
Atmospheric pollution includes smog, acid rain, greenhouse gases, ozone depletion and the effects of carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter. Water pollution covers sewage, industrial waste, eutrophication and treatment stages, while green chemistry focuses on reducing hazardous substances, waste and energy use through safer, more efficient processes.
