Which permanent atmospheric component has the highest proportion by volume?
Answer and explanation
Correct answer: Nitrogen
Nitrogen is the most abundant permanent component of dry air, making up approximately 78% by volume. Oxygen follows at about 21%, argon is just below 1%, and carbon dioxide is present in a much smaller proportion. Because the question asks for the highest volume percentage among permanent gases, option A, nitrogen, is correct. The other gases are important but occur in lower concentrations.
