What is the negative electrode called?

Anode

Cathode

The correct answer is "Cathode." In electrolysis, the negative electrode is referred to as the cathode. The cathode is where reduction reactions occur, meaning electrons are gained.

Option A, "Anode," is actually the positive electrode where oxidation reactions occur, meaning electrons are lost.

Options C and D, "Des-incrustation" and "Iontophoresis," are techniques involving galvanic current and they are not specifically related to the negative electrode in electrolysis.
