The correct option is A Oparin
The theory of biochemical evolution of origin of life was advocated by two scientists working independently: Alexander Oparin - a Russian biochemist, in 1924, and J.B.S. Haldane - an Anglo-Indian biologist, in 1929. Redi and Pasteur are famous for their experiments on the theory of biogenesis, and Darwin is well known for the theory of natural selection.
