Answer:

First of all you wrote text tube which should be TEST tube.....no problem....

Iodine solution turns Starch into color blue-black. So, that tells that Test tube B contained Starch and so turned blue, while Test Tube A didn't contained Starch and so didn't turned Blue.

PLEASE MARK IT AS BEST AND RATE 5 STAR. THANKS!
