Which option gives an incorrect use of an atmospheric gas?
Answer and explanation
Correct answer: Argon—main gas supporting combustion
Argon is a chemically inert noble gas and does not normally support burning. Oxygen is the atmospheric gas that supports combustion, while carbon dioxide is consumed by green plants during photosynthesis. Ozone absorbs much of the Sun’s harmful ultraviolet radiation. Therefore, option D is incorrect because it assigns oxygen’s combustion-supporting role to argon.
