Answer:

D. The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell.

Explanation:

Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.

The answer is D.

Think of the cell membrane as a bodyguard. It lets certain substances such as proteins and much needed vital materials into the cell, but it also rejects and blocks off unwanted substances from going into the cell to protect it.
