It prevents harmful substances from entering a cell

The correct answer is option - d

Explanation:

The cell membrane is the double layer membrane that surrounds the cytoplasm and the cellular organelle of the cell. The cell membrane is also known as the plasma membrane that is composed of proteins and phospholipids which act as the barrier for the cell and surrounding environment.

The phospholipid bilayer is selectively permeable which means it only allows certain molecules to pass in or out of the cell while others are not able to pass through it. This characteristic of the cell membrane help to prevent harmful substances from entering the cell.
