Answer:
Correct Answer: D
Solution:
Miller circulated four gases-methane, ammonia, hydrogen and water vapour in an air tight apparatus and passed electrical discharges from electrodes.
He passed the mixture through a condenser.
He circulated the gases continuously in this way for one week and then analysed the chemical composition of the liquid inside the apparatus.
He found a large number of simple organic compounds including some aminoacids such as alanine, glycine and aspartic acid.
