(B) The primitive atmosphere of the Earth was reducing in nature because it lacked free molecular oxygen $(O_2)$.Instead,it was rich in hydrogen atoms and hydrogen-containing compounds like methane $(CH_4)$,ammonia $(NH_3)$,and water vapor $(H_2O)$.The presence of abundant free hydrogen $(H_2)$ and the absence of oxidizing agents like free oxygen made the environment highly reducing,which facilitated the synthesis of complex organic molecules from simple inorganic precursors.
