THE CORRECT OPTION IS (b)
(b) IRON
Explanation:
- Electrolysis is the method which involves chemical reaction at the electrodes when electric current is passed through them.
- It is used to extract reactive metals from ores.
- The iron metal is less reactive than aluminum, potassium, and sodium.
- Iron is less reactive so it will be difficult to extract it through electrolysis.
- Therefore, option (b) is correct.
