Solution

The correct option is D
Potassium,Sodium and Aluminium

The elements that are at the top in the activity series are highly reactive and hence cannot be reduced from their ores by reducing agents. So, they are extracted by electrolysis. Since Potassium, Sodium, and Aluminum are at the top of activity series, they are highly reactive and hence can be extracted by electrolysis.
