उत्तर
(i) and (iii)
Explanation:
When iodine is added to starch, it turns blue-black in colour. Potato and bread are rich in starch. Therefore, boiled and mashed potato and a slice of bread turn blue-black in colour when tested with iodine. Glucose solution does not change colour because it is a digestive product of starch.
