Solution

The correct option is D $A l, N a, M g, C a$
The electrolysis methods are used for the extraction of highly reactive metals from their ores. $K, A l, N a, M g, C a$ are obtained by electrolysis of their salts as they have more affinity for oxygen than carbon. Hence, Option $D$ is correct.
