The right answer is D.
The cell is a biological unit (living) structural, functional and fundamental living beings, of variable size (between 10 to 100 microns).
Physically, a cell is a compartmentalized compartment by a membrane in which all the molecules are grouped together. A cell is able to fulfill different functions of the body, such as reproduction and growth (multiplication of cells), or even metabolism (sum of catabolism (degradation activity) and anabolism (synthesis activity)) .
The cells are autonomous but remain coordinated with each other to complete tasks together (such as, for example, the coordination of dendritic cells to eliminate a pathogen during an immune reaction).
There are two main types of cell organisms: Eukaryotic cells have a nucleus containing the genetic material. Prokaryotic cells lack nuclei, so their genetic material is free in the cell (eg bacteria).
