Solution
The correct option is C Lignin
The cell membrane (also known as the plasma membrane) is a biological membrane that separates the interior of all cells from the outside environment. The principal components of the plasma membrane are lipids (phospholipids cholesterol), proteins, and glycolipids. Lignin is not present in the cell membrane because Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity So, the correct answer is 'Lignin'.
