(D) suberin
Cellulose is the basis of the cell wall present in plants. The cell wall of almost all organisms is made up of cellulose, while lipids along with some proteins form the basic building blocks of the plasma membrane. The plasma membrane is semipermeable and is not impermeable to water.
Lignin is a complex polymer that acts as a cement and hardens the cell wall. It provides flexibility, great tensile and compressive strength to the cell wall and makes the cell wall impermeable. It is present in sclerenchyma cells and not in cork cells. The walls of cork cells are much thicker than suberin, an organic material. Suberin makes these cells impervious to water and gases.
