Which one of the following statements is correct about camphor and ammonium chloride?

Both camphor and ammonium chloride undergo sublimation.
Sublimation is the process where a substance transitions directly from the solid to the gas state, without passing through the liquid state. Both camphor and ammonium chloride exhibit this property under appropriate conditions.
Camphor (Cโ‚โ‚€Hโ‚โ‚†O) is an organic compound. Ammonium chloride (NHโ‚„Cl) is an inorganic compound. Therefore, statements A, B, and D are incorrect. Camphor sublimes readily at room temperature, while ammonium chloride sublimes upon heating.
