Answer:
Option (A) is the correct answer.
Explanation:
Dinitrogen and Dioxygen are main constituents of air but these do not react with each other to form oxides of nitrogen because the reaction is endothermic and requires very high temperature.
Endothermic is a chemical or physical reaction which absorbs and release heat from its surrounding. E.g. melting of ice or dissolving ammonium chloride solvent in water.
