Solution
The correct option is A Artificial synthesis
According to Oparin's theory life originated on early earth through physicochemical processes of atoms combining to form molecules, molecules in turn reacting to produce inorganic and organic compounds. Organic compounds interacted to produce all types of macromolecules which organized to form the first living system or cells. Thus according to this theory life originated upon our earth spontaneously from nonliving matter. First inorganic compounds and then organic compounds were formed in accordance with ever changing environmental conditions. This is called chemical evolution which cannot occur under present environmental conditions upon earth. Conditions suitable for origin of life existed only upon primitive earth. Thus, option A is correct.
