Answer:
D - Selective Permeable Membrane.
Step-by-step explanation:
A cell wall is a type of structural layer that surrounds cells, just out the cell membrane. The cytoplasm is a gel-like fluid inside a cell. Hypertonic is a solution containing dissolved particles ( which can be salt or other electrolytes) that can be found in normal cells and blood.
Selective Permeable Membrane is a type of membrane that allows only some molecules and substances to pass into or leave a cell, while others can not.
