Text Solution

Verified by Experts

The correct Answer is:
B
Polysaccharide are complex carbohydrates which are formed by polymerisationof large number of monosaccharide monomers. Exoskeletons of arthropods, contain a complex polysaccharide called chitin. These complex polysaccharides are heteropolymers. Plant cell walls are made up of cellulose. Paper made from plant pulp and cotton fibre is cellulosic. Cellulose is homopolysaccharide.
