The correct option is D Glycosidation
Golgi apparatus receives materials from the cytosol and endoplasmic reticulum in the form of transitional vesicles. The latter fuse with the cisterna of convex forming face. Both membranes and biochemicals flow to the distal cisternae for elaboration. Golgi apparatus processes materials for secretion and formation of membranes. The production of complex biomolecules like glycoproteins and glycolipids occurs through the process of glycosylation in Golgi apparatus.
