Amylose, amylopectin and glycogen are each polysaccharides. Enzyme X hydrolyses $\alpha$-1,4-glycosidic bonds at the ends of a polysaccharide molecule, releasing one maltose molecule at a time. Which row indicates how completely each of these molecules will be hydrolysed by enzyme X? (Assume that each polysaccharide contains the same number of monomers before hydrolysis starts.)
- Aleast completely hydrolysed: amylose, intermediate: amylopectin, most completely hydrolysed: glycogen
- Bleast completely hydrolysed: amylose, intermediate: glycogen, most completely hydrolysed: amylopectin
- Cleast completely hydrolysed: glycogen, intermediate: amylose, most completely hydrolysed: amylopectin
- Dleast completely hydrolysed: glycogen, intermediate: amylopectin, most completely hydrolysed: amylose
