How does the abundance of nitrogen in the atmosphere prevent combustion from becoming uncontrolled?
Answer and explanation
Correct answer: It dilutes oxygen and balances reactivity
Nitrogen is comparatively unreactive under ordinary atmospheric conditions and forms the largest part of air. By mixing with oxygen, it lowers the effective concentration of oxygen available to burning materials and absorbs some heat, so combustion remains limited rather than spreading uncontrollably. Option A is correct; nitrogen does not create fuels, send fire away, or destroy water vapour.
