The polymer of fructose is

The correct option is B inulin
Polysaccharides are long chains of sugars. Inulin is a polymer of fructose.
Starch, glycogen and cellulose are all polymers of glucose. Starch is the stored form of sugars in plants and is made up of a mixture of two polysaccharides, amylose and amylopectin (both polymers of glucose).
Glycogen is the storage form of glucose in humans and other vertebrates. Like starch, glycogen is a polymer of glucose monomers, and it is even more highly branched than amylopectin.
Cellulose is made up of unbranched chains of glucose monomers.
