(A) Camphor
(B) Sugar
(C) Sulphur
(D) None of these
🧠 Explanation:
- Sugar is highly soluble in water due to its polar nature, which easily interacts with water molecules.
- When sugar is added to water, hydrogen bonding occurs between water and sugar molecules, allowing it to dissolve quickly.
- In comparison, camphor and sulphur are non-polar or less polar, making them poorly soluble in water.
- Therefore, among the given options, sugar is the most soluble in water, making (B) the correct answer.
