| I: | Cellulose is a polymeric polysaccharide consisting of only one type of monosaccharide. |
| II: | Starch is a homopolymer. |
| III: | Inulin is a polymer of fructose. |
| IV: | In glycogen, the right end is called the reducing end, and the left end is called the non-reducing end. |
| Assertion (A): | The starch-I2 is blue in colour. |
| Reason (R): | Starch forms helical secondary structures and can hold I2 molecules in the helical portion. |
| 1. | (A) is True but (R) is False. |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is False but (R) is True. |
| 4. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
