Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Recall the set-up:
In 1953, S. L. Miller created conditions of the early earth in a closed flask. He passed electric discharge through a gas mixture at 800 degrees Celsius.
Step 2: List the gases used:
The gases were methane (\( CH_4 \)), ammonia (\( NH_3 \)), hydrogen (\( H_2 \)) and water vapour.
Step 3: Pick the odd one:
Carbon dioxide (\( CO_2 \)) was not in the mixture. So (A), (B) and (C) were used, and (D) was not.
Final Answer:
The correct option is (D) Carbon dioxide.
