Argon belongs to which category of gas in the atmosphere?
Answer and explanation
Correct answer: Noble or inert gas
Argon is classified as a noble or inert gas because its atoms are chemically unreactive under ordinary atmospheric conditions. It forms about 0.93% of dry air and is considered a permanent atmospheric component rather than a variable gas. Therefore option B is correct. Oxygen is important for respiration but is not argon; water vapour is the common variable gas, and argon is not normally identified as a major greenhouse gas.
