A Correct answer
Explanation

Salt (NaCl) dissolves fastest in water because it's an ionic compound that readily dissociates into Na+ and Cl- ions when in contact with water. Sugar takes longer to dissolve, baking powder is a mixture that reacts before fully dissolving, and chalk powder is mostly insoluble in water. The ionic nature of salt makes it highly soluble with quick dissolution kinetics.
