The idea that life arose through a long series of chemical reactions from non-living inorganic molecules was proposed by which pair of scientists?

1. The chemical evolution theory says life began from non-living inorganic molecules through chemical reactions. 2. This idea was developed by Oparin (1922) and Haldane (1929). 3. Watson and Crick described the DNA model, not the origin of life, which rules out option A. 4. So the answer is Oparin and Haldane, option B. _Source: Samacheer Kalvi (TN SCERT) Class 10 Science, Unit 19 Origin and Evolution of Life "Chemical Evolution of Life", p.282_
