Why is argon mentioned in atmospheric composition after nitrogen and oxygen?
Answer and explanation
Correct answer: Because it is the third major permanent gas in dry air
The governing concept is the composition of dry air. Nitrogen and oxygen make up most of the atmosphere, while argon is the next most abundant major permanent gas, although its proportion is much smaller. It is chemically inert and does not generate rainfall. Water vapour is variable, whereas argon is generally treated as a stable constituent, so options B, C, and D are incorrect.
