The chewed rice will not turn into blue color whereas boiled rice will turn into blue color due to the presence of iodine solution in it.
Starch is found in the chewed rice.
The iodine test is usually performed to check the presence of starch content.
Starch turns into deep blue-black color upon adding aqueous solution into it.

Answer:
In test-tube A, the boiled rice contains starch. When we add 1-2 drops of iodine, the combination turns in the shade of blue-black. This indicates the presence of starch in the test tube A.
In test-tube B, the starch of rice converts into sugar on digestion. Thus, the colour of iodine will not change.
