Solution

The correct option is C A, B and C
Oparin and Haldane suggested that simple inorganic molecules could have reacted to form simple organic monomers like amino acids and nucleotides.
This is how the first non-cellular form of life came into being around 3 billion years ago.

They could grow, reproduce their molecules and were able to maintain an internal environment. They were partially isolated from the surroundings and exhibited a simple form of metabolism. The non - cellular life form eventually evolved into the first cellular form of life around 2000 million years ago.
So, the correct answer is option 'c'.
