The correct option is C self-assembly
The large organic molecules which were synthesized abiotically on the primitive earth later came together, and due to intermolecular attraction, they formed large colloidal aggregates. Such water bound aggregates have been named microspheres. A liposome is a spherical vesicle having at least one phospholipid bilayer. Coacervate is an aggregate of macromolecules, such as proteins, lipids, and nucleic acids, that form a stable colloid unit with properties that resemble living matter. So, the correct option "self-assembly".
