Option 1 is the correct sequence based on the Miller-Urey experiment which recreated fundamental conditions of primitive Earth. First, Methane and Ammonia are considered as the initial gases present. These gases under specific conditions form Hydrogen cyanide and other simpler organic compounds. From these simpler molecules, Nitriles, complex organic compounds containing a cyano functional group, are created. Finally, Amino acids are developed from these nitriles under certain conditions.

Option 2, 3, and 4 are incorrect as they do not follow the logical progression of the formation of organic compounds under primitive earth conditions. Option 2 starts with Hydrogen cyanide, a product of the reaction between the initial gases, which makes the sequence incorrect. Option 3 and 4 put Amino acids and Nitriles respectively, before Methane and Hydrogen cyanide, which is not possible because the latter two are simpler compounds and are the precursors for the former.
