The compound in choice D, which is the shortest chain alcohol (with the formula indicating a primary alcohol with three carbon atoms, commonly known as 1-propanol), is the most soluble in water due to its ability to form hydrogen bonds with water molecules. Shorter chain alcohols are generally more soluble in water than longer chain alcohols because the hydroxyl (-OH) group is more effective at forming hydrogen bonds with water in shorter chains.
