Hint: First of all Origin of life starts in water in non-cellular form about 3000 million years ago. These were formed from the aggregation of molecules.

Complete step by step answer:
First of all chemical evolution has started on the earth. The theory of chemical evolution was proposed by Oparin and Haldane and its experimental proof was given by Urey and miller. According to them, in primitive earth, the condition was very harsh, like reducing the environment, Very high temperature, volcanic eruption, and abundance of the gases like $C{H_4}, N{H_3}$ etc. Urey and miller also created the similar condition in the laboratory, after some times they saw that amino acid, lipids, Nucleotides, hydrocarbon chain has been formed from the molecules such as $C{H_4}, N{H_3}$, ${H_2}O$, etc. and after some days they found that, nucleic acid such as RNA. Protein molecules, Carbohydrates were formed. After their formation , the first non-cellular life formed, which was thought to be the precursor of cellular life forms.
So, the correct answer is option (C).

Note: First non-cellular life forms appear and scientists call them with different names like protocells, protobionts, micro drop, microsphere, etc. Oparin called them Coacervates. Coacervates are like a hollow bubble, surrounded by two layers of lipid. These layers used to regulate the molecule entering into it (same as plasma membrane do, but they were not plasma membrane). They used to grow and divide into smaller coacervates.
