How does nitrogen prevent combustion from becoming too intense?
Answer and explanation
Correct answer: It is less reactive and dilutes oxygen
The governing concept is the role of atmospheric nitrogen as a comparatively unreactive diluent. Nitrogen occupies about 78% of air and reduces the concentration of oxygen available to support burning, so combustion is generally less rapid and less intense; therefore option A is correct. It does not produce all oxygen, solidify water vapour, or transform ozone into anything described by the other options.
