Answer: 3
Explanation:
3) both electrolytic cells and voltaic cells
The statement, that describes reduction occurs at the cathode is "both electrolytic cells and voltaic cells."
What is a reduction?
The gain of electrons is referred to as reduction. The species that is being oxidised is also known as the reducing agent or reductant, whereas the species that is being reduced is known as the oxidising agent or oxidant.
Reduction takes place at the cathode electrode whereas oxidation occurs at the anode in both galvanic and electrolytic cells, and electrons travel from the anode to the cathode.
Electrons must move toward the location of reduction since reduction is the addition of electrons. The negative charge is on the cathode of an electrolytic cell, while the positive charge is on the anode.
Hence, the correct answer is 3.
