A is true but R is false. Rusting of iron is a chemical process but not endothermic; it is a slow exothermic reaction, releasing little heat. Since the heat released is negligible, it often goes unnoticed, making the given reason incorrect.

    1. Rusting of iron occurs when iron reacts with oxygen and moisture, forming hydrated iron oxide. This reaction is exothermic, though very slow, so heat release is hardly noticed. Therefore, the statement that rusting is endothermic is false, while the reason provided is also incorrect. Thus, the correct answer is C. Assertion is true but Reason is false.
