The correct option is B Endoplasmic reticulum
The Golgi apparatus is a part of the endomembrane system. The system consists of endoplasmic reticulum, Golgi apparatus, lysosome and plasma membrane. The Golgi apparatus receives materials from the cytosol and endoplasmic reticulum in the form of transitional vesicles. The vesicles move to the forming face of the Golgi bodies and fuses there with existing cisternae and help in the growth of the organelle.
