What is the most correct way to identify argon in the atmosphere?
Answer and explanation
Correct answer: A permanent inert gas
Argon is a chemically unreactive noble gas and is treated as a permanent constituent of dry atmospheric air. It forms slightly less than one percent of dry air, so it is much more abundant than many trace gases, but it is not classified as a major greenhouse gas. Option B is therefore correct; the other descriptions refer to different atmospheric roles or substances.
