b. warm, wet, and cloudy


c. cool, wet, and cloudy


d. warm, dry, and sunny


e. warm, wet, and sunny

Answer 1

The answer is; E

The key word is photochemical smog that differentiated it from industrial smog that are formed from different conditions. Photochemical smog is majorly driven by the sun that splits nitrogen oxide pollutants in the air into nitrogen and oxygen. The oxygen forms OH radicals with the water vapour in the air. The OH forms radicals with hydrocarbons pollutants in the air which ultimately form aldehyde peroxides that are a health risk.
