Which gas supports combustion in the atmosphere?
Answer and explanation
Correct answer: Oxygen
Oxygen supports combustion because most fuels burn by reacting with oxygen and releasing heat and light. Therefore, option D is correct. Nitrogen and argon are largely inert under ordinary burning conditions and do not sustain a flame. Carbon dioxide generally does not support combustion and can help extinguish fires, which is why it is used in some fire extinguishers. Oxygen is only a supporter, not the fuel itself.
