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

When calcium carbonate is heated, it breaks down to form calcium oxide and carbon dioxide. Thermal decomposition is the process in which heat is required. It is also known as thermolysis. It is a process in which a compound breaks into two or more products when heat is supplied. This reaction is used for the production of oxygen. This reaction is also used for the production of acidic as well as basic oxides. CaCO3 on thermal decomposition gives:
CaCO3 → CaO + CO2
CaO → Basic oxide.
CO2 → Acidic oxide.
Hence option C is correct.
