Endomembrane system are found in the endoplasmic reticulum and golgi apparatus. The major components of the endomembrane system are golgi apparatus, endoplasmic reticulum, vessicles, cell membrane and the nuclear membrane.
The primary function of the endomembrane system is to produce, sort, and package materials. This system includes the nuclear envelope, endoplasmic reticulum, Golgi apparatus, vesicles, lysosomes, and the plasma membrane. Therefore, the correct choice is A: producing, sorting, and packaging material.
