Solution
The correct option is B Chemoheterotrophs
The first living beings were prokaryotes, like bacteria. They were single-celled. Nucleic acid core consisted of naked DNA. These living beings were present in the environment of the soupy sea having abundant organic molecules. Nutritionally they were chemoheterotrophs. They absorbed the organic materials from outside both for body building and liberation of energy. Respiration was anaerobic since free oxygen was absent in the environment.
