Vedclass · Answer

(C) The primitive atmosphere was composed of light atoms like hydrogen,which were highly reactive. These hydrogen atoms combined with all available oxygen atoms to form water $(H_2O)$,leaving no free oxygen in the atmosphere. Therefore,the primitive atmosphere was reducing in nature.The formation of the ozone layer $(O_3)$ is a result of the modern oxidizing atmosphere,which contains abundant free oxygen produced by photosynthetic organisms. In the primitive atmosphere,there was no free oxygen available to form ozone. Thus,the Reason is incorrect.

Assertion: The primitive atmosphere was a reducing one,i.e.,without oxygen.
Reason: In the primitive atmosphere,oxygen was involved in forming ozone.
