Which gas has the highest proportion in dry air?
Answer and explanation
Correct answer: नाइट्रोजन — Nitrogen
The governing concept is the percentage composition of dry air, in which water vapour is excluded. Nitrogen makes up approximately 78% by volume, oxygen about 21%, argon about 0.93%, and carbon dioxide only a very small fraction. Since 78% is the largest share, option A is correct. Oxygen is second, while argon and carbon dioxide are trace constituents, so the distractors represent smaller proportions.
