Vedclass · Answer

(D) The atmosphere of primitive Earth was a reducing atmosphere.According to the Oparin-Haldane hypothesis and the Miller-Urey experiment,the primitive atmosphere contained gases like methane $(CH_4)$,ammonia $(NH_3)$,water vapor $(H_2O)$,and hydrogen $(H_2)$.Free oxygen $(O_2)$ was absent in the primitive atmosphere because it was highly reactive and was consumed in the formation of water and oxides.Since none of the options ($CH_4$,$NH_3$,$H_2O$) represent free oxygen,all of these were present.Therefore,the correct answer is that none of the listed options were absent.

Which of the following was absent in the atmosphere of primitive Earth?
