The correct option is D Chemical origin
Chemical evolution describes how life originated on earth, the atmosphere which prevailed on earth during that time. according to it, the prokaryotes are the oldest living organism. According to this theory, the earlier environment provoked the synthesis of simple organic substance like amino acids etc. This theory states that early environment was rich in ammonia, water vapour, methane etc. Oxygen was lacking in the environment. It is believed that the UV rays from sun helped in the synthesis of an organic molecule. Thus the correct option is D.
