Answer:
The answer is letter A.
Explanation:
Iodine does not dissolve in water because water is an extremely polar molecule, while iodine exists in the diatomic form of I2 , and is therefore non-polar, and will not dissolve in water. Ethanol has some polarity in its OH bond, but the C2H4 bond is non-polar, and therefore iodine has slight solubility in ethanol.
