Which one is not found in the composition of plasma membrane?

The correct answer is A. Minerals.

A plasma membrane is a thin, flexible barrier that surrounds all cells. It protects the cell from its environment and allows it to exchange materials with its surroundings. The plasma membrane is composed of a phospholipid bilayer, which is a double layer of phospholipid molecules. Phospholipids are molecules that have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophilic heads of the phospholipids face the inside and outside of the cell, while the hydrophobic tails face each other in the middle of the membrane.

In addition to phospholipids, the plasma membrane also contains proteins and carbohydrates.
