Life cannot originate from inorganic materials now because of
Open in App
Solution
The correct option is B High atmospheric oxygen
Conditions of primitive earth for origin of life
The primitive atmosphere was reducing in nature as there was abundant hydrogen. Since oxygen gas was absent, the formation of organic compounds from inorganic molecules took place easily which led to the formation of the first living cell.
Prevailing environmental conditions
Earth cooled down with the passage of time and the temperature dropped.With the increase in the number of autotrophs the amount of oxygen increased. The presence of an oxidizing environment was not conducive for the formation of organic compounds and thus not favourable for the origin of life.
Final answer
(c) High atmospheric oxygen
