Correct Answer

Explanation

In an electrolytic cell, where electrical energy is used to drive a non-spontaneous chemical reaction, the species that migrate to the anode are usually negatively charged ions (anions). This is because during electrolysis, positive electrical charge (cations) is attracted to the cathode (negative electrode), and negative electrical charge (anions) is attracted to the anode (positive electrode).

So, in summary, in an electrolytic cell, anions migrate to the anode.
