Solution
The correct option is A Water, methane, hydrogen sulphide and ammonia
Miller and Urey conducted an experiment in 1953 to test the idea that organic molecules can be synthesised in a reducing environment. They assembled an atmosphere similar to the one that was thought to exist on primitive earth. They added a mixture of ammonia, methane and hydrogen sulphide over water. There was no oxygen. This was maintained at a temperature just below 100°C and sparks were passed through the mixture of gases to simulate lightning. At the end of a week, 15% of the carbon (from methane) had been converted to simple organic compounds of carbon.
