Solution

The correct option is A
semipermeable

A semipermeable membrane is a membrane that allows certain types of molecules to pass through. Body cells are surrounded by this type of membrane. By serving as a barrier between the interior and the exterior of the cell, it protects the cell from foreign bodies that could be harmful. Outside the body, these membranes are artificially created and they are used for specific functions such as water desalination and purification.
