The primary difference between a homopolysaccharide and a heteropolysaccharide lies in the

A. Type of glycosidic bond linking the monomer units
B. Identity of the monosaccharide monomer units that make up the polymer
✓
C. Degree of branching within the polymer chain
D. Molecular weight and solubility of the final polymer

📝 Explanation

A homopolysaccharide is composed of a single type of monosaccharide monomer (e.g., starch, cellulose, glycogen are all made of glucose). A heteropolysaccharide contains two or more different types of monosaccharide units (e.g., peptidoglycan, agar, hyaluronic acid).
