The presence of nitrogen as nearly four-fifths of the atmosphere gives what kind of stability?
Answer and explanation
Correct answer: It prevents air from becoming highly reactive
Nitrogen makes up about 78% of dry air and is comparatively unreactive under ordinary atmospheric conditions. Its large proportion dilutes more reactive gases, especially oxygen, so the atmosphere does not become excessively reactive or support uncontrolled burning. Option A expresses this stabilising role. Nitrogen does not permanently remove clouds, freeze oceans or alter Earth’s orbit, making options B, C and D irrelevant.
