Solution
The correct option is A i, ii and iii Ionic salts are soluble in water and they have large solubility because of high dielectric constant value of water, and after dissolving salts in water they are converted into ions and ions are a good conductor of electricity, the lowering of freezing point and increasing in boiling point can be explained by their colligative properties.
