Solution

The correct option is A True
The metals high up in the reactivity (Na, Mg, Ca, Al) series are very reactive. They cannot be obtained from their compounds by heating with carbon. This is because their metals have more affinity for oxygen than carbon. These metals are obtained by electrolytic reduction.
