Vedclass · Answer

(B) According to the Oparin-Haldane hypothesis,the primitive atmosphere of the Earth was a reducing atmosphere.It contained gases like methane $(CH_4)$,ammonia $(NH_3)$,hydrogen $(H_2)$,and water vapor $(H_2O)$.Free oxygen $(O_2)$ was absent in the early atmosphere because it was highly reactive and would have immediately combined with other elements to form oxides.Therefore,the correct option is $B$.

According to Oparin,which one of the following was absent in the primitive atmosphere of the Earth?
