It would be nice to see the 4 stages titled to have a clue to what they could be. You see, chemical evolution is a myth, like Darwin's "warm little ponds." There are no naturalistic processes that have any power to accomplish the complex, diverse, extensive and highly non-entropic assembly of biochemical elements, molecules and assemblies into even the simplest life.
There is no primordial soup, panspermia is a distraction, none of the intractable issues for the origin of life.
Logically, the first step is collection of all elements, second, first level assembly of amino acids lipid membranes, proteins, third, higher level combination of biochemical molecules and generation of nucleotide coded DNA containing the processing code for generation and production of RNA, enzymes ribozymes and all other cellular functions, then fourth, the execution of all metabolism, nutrient collection, waste elimination and reproduction consistent with a living organism. Admittedly speculative since chemical evolution is a myth.
The following that is not considered as a form of Vitamin A from the give choices is "retinalogic." Retinal is a molecule important for our vision. Retinoic acid regulates the functions of Vitamin A for muscle development. Lastly, retinol is used as a component in dietary supplements.
Are their any choices for this or is this a written response?
