$\large\mathbb \blue{\fcolorbox{blue}{black} { \ VERIFIED\ ANSWER \ }}$

Boil the leaf in water for about 2 minutes. Now, to decolourise the leaf, transfer the leaf from boiling water to a beaker containing ethanol and boil the leaf in a water bath. The area of the leaf that was uncovered performed photosynthesis and will have starch, therefore turned blue-black with iodine solution.
