Correct option: A
CaCO3→CaO+CO2\mathrm{CaC}{\mathrm{O}_3} \to \mathrm{CaO} + \mathrm{C}{\mathrm{O}_2}
Option A (CaCO3→CaO+CO2\mathrm{CaC}{\mathrm{O}_3} \to \mathrm{CaO} + \mathrm{C}{\mathrm{O}_2}) is correct because decomposition reactions generally require energy input to break bonds, making them endothermic.
