Both C and D
Rough endoplasmic reticulum - Formation of carbohydrates
Golgi apparatus - Formation of lipids
Smooth endoplasmic reticulum - Lipid synthesis
Rough endoplasmic recticulum - Protein synthesis
When ribosomes are present in the membrane of the endoplasmic reticulum it is called the rough endoplasmic reticulum. RER is abundantly found in the cells that actively synthesize proteins. The synthesis of lipids takes place in the smooth endoplasmic reticulum. Thus, the correct answer is option E.
