(i)Cellulose is a homopolymer of glucose.
(ii)Inulin is a homopolymer of fructose.
(iii)Starch gives blue colour and glycogen gives red colour with iodine solution.

(iv)Cellulose gives no colour with iodine solution.

• A. Statements (i), (ii) and (iii) are correct
• B. Statements (i), (ii) and (iv) are correct
• C. Statements (ii) and (iii) are correct
• D. All statements are correct

Answer 1

The correct option is D All statements are correct

Cellulose is a polymer of glucose which is formed by Alpha 1-4 glycosidic bonds and cellulose is and an oligosaccharide.

Insulin is a protein which is made up of the amino acid chains.

Starch gives blue colour and glycogen gives red colour with iodine solution because they have branched structure that can trap the iodine molecule.

Cellulose is a linear structure and does not have any branch structure it does not give colour.

So, the correct option is 'All statements are correct'
