Answer:
The correct option is A. A semi-permeable membrane

A semi-permeable membrane can be described as a selective membrane that filters out which molecules to let-in and let-out of the cell. The semi-permeable membrane causes selective molecules or ions to move inside or outside it through processes like diffusion, facilitated diffusion, passive transport, active transport, osmosis etc.
On the other hand, a permeable membrane is not selective and will allow and will let any kind of molecules to pass.
