Amylose being a linear polymer without branching forms a helical shape in which iodine fits well, while iodine cannot bind to the sheet link structure of cellulose. The binding of iodine is mild in case of amylopectin, as amylopectin is a branched chain molecule, so cannot trap the molecule of iodine, meaning the colour of iodine remains reddish violet. Hence Amylose gives blue colour, amylopectin gives violet colour and cellulose does not change the colour of iodine.

Explanation:
The given information states that three different tubes labeled A, B, and C contain carbohydrates, and when iodine is added to these tubes, the color changes. Tube A turns blue, tube B turns reddish violet, and tube C remains red (the color of iodine). Based on this information, we can infer the following:
Tube A contained Amylose:
When iodine is added to a solution containing amylose, it forms a complex called amylose-iodine complex. This complex has a blue color. Therefore, tube A, which turned blue upon adding iodine, must have contained amylose.
Tube B contained Amylopectin:
When iodine is added to a solution containing amylopectin, it forms a complex called amylopectin-iodine complex. This complex has a reddish-violet color. Therefore, tube B, which turned reddish violet upon adding iodine, must have contained amylopectin.
Tube C contained Cellulose:
Cellulose does not form a complex with iodine and does not change color upon adding iodine. Therefore, tube C, which remained red (the color of iodine) upon adding iodine, must have contained cellulose.
Conclusion:
Based on the information provided, we can conclude that:
- Tube A contained Amylose.
- Tube B contained Amylopectin.
- Tube C contained Cellulose.
Therefore, the correct answer is option 'A,B,C'.
