Biosynthesis of all N-linked oligosaccharides begins in the rough ER with a preformed branched oligosaccharide precursor Glc3Man9(GlcNAc)2, Which of the following statements is incorrect about these biosynthesis?

a) the oligosaccharide precursor is assembled on a membrane- attached anchor called dolichol phosphate

b) First sugar residue is attached to dolichol by a glycosidic bonds & the other

sugars are added by high-energy pyrophosphate

c) Two N- acetylglucosamine (GlcNAc) and five mannose residues are added one at a time to a dolichol phosphate on the lumen

d) Four mannose and three glucose  residue are added one to a dolichol phosphate on the luminal side
