Vedclass · Answer

(B) On the primitive Earth,the atmosphere was reducing in nature. As oxygen was released through various chemical processes,it reacted with hydrogen-containing compounds like methane $(CH_4)$ and ammonia $(NH_3)$. Specifically,oxygen combined with hydrogen atoms derived from these organic molecules to form water $(H_2O)$ and carbon dioxide $(CO_2)$. Therefore,the correct option is $B$.

On primitive Earth,oxygen combined with $........$ to produce water and carbon dioxide.
