Solution
The correct option is B
Reduction
Explanation:
Electrolysis:
Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form.
Reduction:
Reduction is the gain of electrons or a decrease in the oxidation state of a chemical or atoms within it.
In the process of electrolysis, there is an exchange of ions and atoms due to the addition or removal of electrons from the external circuit.
On passing current, cations move to the cathode, take electrons from the cathode (given by the supply source battery), and discharged into the neutral atom.
The neutral atom, if solid, is deposited on the cathode, and if gas moves upwards.
This is a reduction process and the cation is reduced at the cathode.
