Which gas is found in the largest amount in the atmosphere?
Answer and explanation
Correct answer: Nitrogen
Nitrogen is the most abundant gas in Earth’s dry atmosphere, making up approximately 78% by volume. Oxygen contributes about 21%, while carbon dioxide and ozone occur in much smaller quantities. Therefore, option B is correct. The question asks for the largest proportion, not the gas most directly used in respiration; that distinction explains why nitrogen, rather than oxygen, is selected.
