Which of the following correctly represents a structural polysaccharide, its monomeric unit, and the primary bond linking its monomers?

Step-by-step solution

Chitin is a structural polysaccharide found in the exoskeletons of arthropods and cell walls of fungi. It is a homopolymer of N-acetyl glucosamine (NAG) monomers linked by glycosidic bonds. Cellulose is a structural polysaccharide, but its monomer is glucose, not fructose. Glycogen is a homopolymer of glucose with glycosidic bonds, but it functions as a storage polysaccharide in animals, not a structural one. Although chitin contains nitrogen in its modified sugar monomers, the monomers themselves are linked by gly
