Hint:A cell is the basic structural, functional, and biological unit of life. Cells are often referred to as “building blocks of life”. The study of cells is known as cell biology or cytology. The number of cells varies from species to species. Cells were discovered by Robert Hooke in 1665. Cells are not visible by naked eyes. The electron microscope, light microscope, etc. are used to see cells.

Complete answer:Option A- Coacervates
These are small, liquid droplets of two immiscible liquid phases. Coacervates are found in various biological processes like surface adhesion, self-assembly, vesicle formation, and cell replication. These are also associated with intracellular protein aggregation.
Option B- Protocell
It is a self-organized endogenously ordered spherical group of lipids. These are structures which are formed by aggregation of non-living components.
Option C- Protobiont
These are the aggregation of organic molecules that are surrounded by a membrane. These are precursors of prokaryotic cells.
Option D- Both B and C
As explained in Option B and C. Protocell is also known as Protobiont.

Thus, the correct option is Option D- Both B and C.

Note- Prokaryotes are cellular organisms that do not have an envelope-enclosed nucleus. They lack mitochondria and other membrane-bound organelles. They reproduce through Asexual reproduction, usually by binary fission. For example- E. coli, Streptococcus bacterium, Archaea.
Eukaryotes are cellular organisms in which the nucleus of the cell is enclosed within a nuclear envelope. These cells contain membrane-bound organelles such as Mitochondria, Golgi apparatus, etc. For example- Protists, fungi, plants.
