Solution

The correct option is B Iodine solution
Dilute iodine solution is used to test the presence of starch in solutions. 2-3 drops of iodine solution are added to the solution to be tested. A blue-black colour appears if starch is present. In the absence of starch, the solution exhibits the golden yellow colour of iodine solution.
