In an electrochemical cell, the correct answer is:

a. Chemical energy gets converted into electrochemical energy

Here's why:

An electrochemical cell is a device that produces an electric current from energy released by a spontaneous redox reaction, this means that it converts chemical energy into electrical energy. This happens when a fuel (like hydrogen) is passed over an anode and an oxidant (like oxygen) is passed over a cathode and the two are connected by an electrolyte. The fuel is oxidized at the anode, releasing electrons, which travel through an external circuit (doing work along the way) to the cathode, where the oxidant is reduced, absorbing the electrons. The electrolyte allows ions to flow between the anode and cathode, maintaining a neutral charge in both compartments. This flow of electrons from the anode to the cathode is an electric current, which can be used to do work.
