The correct description of the cell membrane is:

It is a double layer of phospholipids.

The cell membrane, also known as the plasma membrane, consists primarily of a phospholipid bilayer, which forms the structural foundation of the membrane. This bilayer also contains proteins, cholesterol, and carbohydrates, allowing it to function as a selectively permeable barrier and play a role in communication and signaling within and between cells.
