Which is the correct order of gases by amount in the atmosphere?
Answer and explanation
Correct answer: Nitrogen, oxygen, argon
By volume in dry air, nitrogen is the most abundant gas, followed by oxygen and then argon. Nitrogen makes up about 78%, oxygen about 21%, and argon roughly 0.93%; the remaining fraction includes gases such as carbon dioxide. Hence option B gives the correct decreasing order. The other choices reverse major gases or place carbon dioxide incorrectly at the top.
