Answer: B. Water molecules surround solute molecules.
In the solubility of substances, the law that “like dissolves like” is strictly adhered to. Polar compounds are therefore soluble in polar solvents and non-polar compounds are soluble in non-polar solvents. Water is a polar solvent and then an excellent solvent for polar solutes. Water cannot dissolve non-polar solutes. When polar solutes are dissolved in water, they are surrounded by water molecules and as a result of the high dielectric constant of water, the polar molecules are separated from one another and eventually get dissolved in the water.
