How does the large amount of nitrogen affect combustion in the atmosphere?
Answer and explanation
Correct answer: It dilutes oxygen and keeps combustion controlled
Option B is the best answer because nitrogen is relatively unreactive under ordinary atmospheric conditions and makes up most of the air. By mixing with oxygen, it lowers the effective concentration of oxygen and moderates the speed and intensity of combustion. It does not normally extinguish every fire immediately, convert gases into water vapour, or directly form the ozone layer. Those claims confuse nitrogen with other atmospheric processes.
