Calcination is a process in which a substance is heated strongly in the absence of air or oxygen to remove volatile substances or to cause chemical changes. In this case, MgCO3 is heated to form MgO and CO2, which is an example of calcination. The other options involve different chemical reactions and are not examples of calcination.
