Solution

The correct option is D Adenine
The primary objective of Miller-Urey's experiment was to explain the origin of life in the primitive earth by recreating primitive earth like conditions and thereby analyzing the products obtained by the process for signs of origin of life. One of the main products obtained by the process was adenine. Adenine is one of the nitrogen bases making up the genetic material, whether it be DNA or RNA. Hence the presence of Adenine in the primordial soup proves the possibility of formation of hereditary material in the early stages of biological evolution. So, the correct answer is 'Adenine'.
