Solution

The correct option is A Electrolysis
Metals like sodium (Na), magnesium (Mg), and aluminium (Al) are very reactive. So, they are not available in free state and cannot be obtained from their compounds by simple heating. These metals are obtained only by the electrolysis of their molten salts.
