An ionic bond is a bond which occurs when there is a
difference in the electronegativity of the atoms. One atom which has a stronger
electronegativity tends to steal the electron of the other less electronegative
atom hence making it more negative (anion), while the other becomes a cation.
So answer is:

Answer:
b. cellulose.
Explanation:
Cellulose is a polysaccharide consisting of a long chain of repeating glucose units (i.e., β-D-glucose units) that produce long unbranched chains. Cellulose can be considered as a natural polymer (i.e., a non-modified carbohydrate) because it is composed of repeated chains of β-D-glucose molecules stuck together. The cellulose polysaccharide is a principal component of plant cell walls.
