D.) A spontaneous redox reaction converts chemical energy into electrical energy.
InesWalston

Answer: option D

Explanation:

It convert the chemical energy into electrical energy by spontaneous redox reaction inwhich oxidation Occurs at anode and Reduction Occurs at cathode.

Daniel cell is the best example for Voltaic cell which has CuSO4 solution in cathode compartment and ZnSO4 solution in anode compartment

Cell representation: Zn/Zn+2(aq)//Cu+2(aq)/Cu(s)
