Options
- A(A)-(III), (B)-(IV), (C)-(I), (D)-(II)
- B(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- C(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- D(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Correct answer
B. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
Step-by-step solution
Inulin is a polymer of fructose. Therefore, (A) matches with (IV). Chitin is a complex structural polysaccharide found in the exoskeleton of arthropods and is a homopolymer of N-acetyl glucosamine. Therefore, (B) matches with (III). Cellulose is a linear polymer that does not contain complex helices and hence cannot hold iodine molecules. Therefore, (C) matches with (II). Starch forms helical secondary structures and can hold iodine molecules in the helical portion, which gives a blue colour. Therefore, (D) matches
