Sugars are technically called carbohydrates, referring to the fact that their formulae are only multiples of C(H2O). Hexose therefore has six carbons, twelve hydrogen and six oxygen atoms. Glucose is a hexose. Choose from among the following another hexose.

1. Fructose 2. Erythrose
3. Ribulose 4. Ribose

Consider the given two statements:
Statement I: Iodine test can detect the presence of starch but not of cellulose in a given sample.
Statement II: Starch forms helical secondary structure and can hold iodine molecules while cellulose does not contain complex helices and hence cannot hold iodine.
 
1. Both Statement I and Statement II are correct and Statement II correctly explains Statement I
2. Both Statement I and Statement II are correct but Statement II does not correctly explain Statement I
3. Statement I is correct but Statement II is incorrect
4. Statement I is incorrect but Statement II is correct
