Solution

The correct option is D Glycogen, cellulose and starch.
Polysaccharides: It consists of more than six molecules of a monosaccharide joined together by glycosidic bonds with a loss of water each time a monosaccharide is added.
A. Sucrose: disaccharide , glucose:monosaccharide ,Frustose:monosaccharide .
B. Maltose:disaccharide ,lactose:disaccharide , Frustose:monosaccharide.
C. Glycogen:Polysaccharides,Sucrose: disaccharide,Maltose:disaccharide.
D. Glycogen: Polysaccharides, Cellulose: Polysaccharides, Starch: Polysaccharides
So, the correct answer is 'Glycogen, cellulose and starch'.
