How should air be correctly understood?
Answer and explanation
Correct answer: A mixture of gases and fine particles
Air is not a single pure substance. It is a mixture containing nitrogen, oxygen, argon, carbon dioxide, variable water vapour, and small suspended particles such as dust and aerosols. Because several gases and particles occur together, option A gives the correct description. Options B and C name only one component, while option D describes only one minor constituent.
