Solution

The correct option is C Eobiont
The theory of the chemical origin of life stated that life originated from the simple inorganic chemical which formed the complex organic molecules. The complex organic molecules act as a precursor for the origination of life.
  • Eobiont is a hypothetical primordial life-form or chemical precursor to a living organism.
  • Eubionts are the first life form which was anaerobic, heterotrophs and performed chemosynthesis at the initial stage but turned photosynthetic at the later stage.
  • Protobiont is a self-organized, endogenously ordered, spherical collection of lipids proposed as a stepping-stone to the origin of life.
  • True biont is formed by the cooperative interactions between the membrane and encapsulated contents of the probiont.
So, the correct answer is option C.
