Solution

The correct option is D Endoplasmic reticulum
Plasma membrane is a living, delicate, elastic, selectively permeable membrane. Chemically, it is made up of 75% phospholipid. In addition to phospholipid, the membrane contains proteins, cholesterol and polysaccharides. Membrane synthesis or membrane biogenesis is a dynamic process, i.e., some of the membrane proteins and lipids are replaced with newly made proteins and lipids. This is an ongoing process. Some of the proteins and lipids required for membrane biogenesis are synthesized by endoplasmic reticulum.
