Hint: Electrons flow from the negative to a positive end.

Step 1: A cell in which Electrical energy is used to cause a non-spontaneous oxidation and reduction reaction is called an Electrolytic cell. The electrolytic cell requires an energy input to proceed.

Step 2:  Electrolytic cell contains three parts Cathode, Anode, and electrolyte.
  • Positive electrode is called anode.
  • Negative electrode is called Cathode.
  • An electrolyte is a  substance in an aqueous or molten form that dissociates into ions and conducts electricity.
  • In a electrolytic cell, electrons are transferred from cathode to anode through internal supply.
Final answer: Therefore, the correct option is "C".
