4 none of these
Explanation:
nitrogen Nitrogen is important gas of which about 78% of the atmosphere's volume is made up. Nitrogen serves mainly as a diluent. It is relatively inactive chemically, though many of its compounds are very active. Its main function in the atmosphere is to regulate combustion by diluting oxygen. It also indirectly helps in oxidation of different kinds.
