Solution

The correct option is A $N H_{3}, H_{2} O, C H_{4}, H_{2}$
Stanley Miller in $1953$ took an air tight apparatus and circulated four gases - $C H_{4}, N H_{3}, H_{2}$ and water vapour through it. He passed electrical discharges from electrodes at $800^{\circ} C$ . Then he passed the mixture through a condenser. He performed this experiment continuously in this way for a week and analysed the composition of the liquid inside the apparatus. He found a large number of simple organic compounds including some amino acids such as alanine, glycine and aspartic acid. Miller, thus, proved that organic compounds were basis of life.
So, the correct answer is ' $C H_{4}, N H_{3}, H_{2}$ and H $_{2} O$ '
