Correct answer is (c) Silver, tin

Easiest explanation: Since atomization results in oxidation of molten metal as it comes in contact with air, it is only used for materials like zinc and cadmium. Electrolysis is a standard electrolytic process which is used for materials like silver and tin. It is advantageous as it produces oxidation resistant powders.
