C Correct answer
Explanation

Dextran is a complex, branched (heteroglycans) homopolysaccharide made of many glucose molecules. Amylopectin is homopolysaccharide of glucose. Chondroitin-4-sulphate heteropolysaccharide is composed of D-glucuronic acid and N-acetyl-D-galactosamine-4-O-sulphate. Heparin is heteropolysaccharides composed of D-glucuronic acid, L-iduronic acid and N-sulpho-D-glucosamine. Hyaluronic acid is heteropolysaccharide composed of D-glucuronic acid and N-acetyl-D-glucosamine. Chondroitin-4-sulphate heteropolysaccharide is  composed of D-glucuronic acid and N-acetyl-D-galactosamine-4-O-sulphate.
