Solution

The correct option is A aluminium
Metals such as sodium, magnesium, calcium, in the reactivity series are very reactive and cannot be obtained from their compounds by heating with carbon. These metals are obtained by electrolytic reduction. This process is used for oxides of highly reactive metals that are above aluminium in the reactivity series.
