A few drops of iodine solution were added to rice water . The solution turned blue black in colour. This indicates the presence of
A. Complex protein
B. Simple protein

Dear student,

The blue - black colour of rice water confirms the presence of starch

When iodine comes in contact with starch, it forms starch Iodide complex which gives blue-black colour.

Thus option C is correct.
