Answer:
D) a redox reaction to produce electricity
Explanation:
Electrolytic cell and chemical cells are the two types of electrochemical cells there is. Electrochemical cells are devices that interconvert electrical eneegy and chemical energy. Electrolytic cells are cells that induce chemical reactions when an electric current passes through them i.e. they need electric energy to generate chemical energy.
On the other hand, chemical cells generate electrical energy by undergoing chemical reactions involving oxidation and reduction of ions i.e. redox reaction. The chemical cell uses the energy that results from undergoing a redox reaction to generate electricity.
