Solution
The correct option is D Oxygen
The first scientific explanation of origin of life was put forward by A.I. Oparin in 1923. J.B.S. Haldane (1928).
According to them primitive atmosphere was reducing atmosphere because hydrogen atoms (most numerous and most reactive) combined with all available oxygen atoms to form water and leaving no free oxygen. Therefore oxygen was not present in the primitive atmosphere of the earth.
