Which of the following on thermal decomposition yields a basic as well as an acidic oxide?

CaCO3⟶ΔCaO Basic oxide +CO2 Acidic oxide CaO is Basic oxide, since its aqueous solution is alkaline in nature CaO+H2O→Ca(OH)2 Bas CO2 is acidic oxide, since its aqueous solution is acidic in natureCO2+H2O→H2CO3 Carbonic acid 2KClO3→MnO22500 C2KClSalt+3024KClO3⟶498∘CKCl+3KClO4 NH4NO3⟶Δ N2Olaughing gas                       Neutral Oxide +2H2ONa2CO3 can't undergo decomposition
