State faraday’s laws of electrolysis.

Hint: We know that the Faraday's laws of electrolysis are seen when in an electrochemical cell. It gives the relation between the amounts of the substance which forms ions when some amount of current passes through the circuit.

Complete step by step answer:
We know that when some current is passed through a circuit, it can initiate a chemical reaction and similarly, a chemical reaction causes ions to move in the solution, which can produce current. This interdependence of electricity and chemical reaction is further studied, under the topic electrochemistry.
The scientist Faraday gave two laws which quantify the electrochemical reaction.
The first law states that:
The amount or the mass $m$ of the substance which is deposited on the electrode is proportional to the charge $Q$ which is passed through the circuit.
$m\propto Q$
$\implies \dfrac{m}{Q}=Z$
Where $Z$ is the constant of proportionality, called the electrochemical equivalent of the substance, it is defined as the amount of substance deposited per unit flow of charge in the circuit.
The second law states that:
When the some amount of current is passed through the series of electrochemical cells, then the mass $m$ of the substance liberated at the electrode is directly proportional to their chemical equivalence $E$
$m\propto E$
Where, chemical equivalence $E$ is given as $E=\dfrac{molar\;mass}{valence}$

So, the correct answer is “Option A”.

Note: We know that an electrochemical cell is a device which can produce an electric current due to the spontaneous chemical reaction of the cell. An example of electrochemical cells are the galvanic cell or voltaic cell. The electrochemical cell has two terminals, namely the anode and cathode. The flow of ions from one terminal to another, causes the current in the given circuit.
