Choose the correct decreasing order of gases in air.
Answer and explanation
Correct answer: नाइट्रोजन — Nitrogen; ऑक्सीजन — Oxygen; आर्गन — Argon; कार्बन डाइऑक्साइड — Carbon dioxide
The governing concept is the composition of dry air by volume. Nitrogen is the most abundant gas, followed by oxygen; argon is present in a much smaller proportion, and carbon dioxide is smaller still. Therefore the decreasing order is nitrogen, oxygen, argon, and carbon dioxide, making option A correct. Option B reverses the first two gases, while C and D place minor gases incorrectly.
