JEE Main Chemistry question

NaOH is prepared by the electrolysis of:

(A)Aqueous solution of sodium chloride with suitable electrodesCorrect
(B)Molten sodium chloride with graphite anode and iron cathode
(C)Sodium carbonate with platinum electrodes
(D)Sodium carbonate with nickel electrodes

Answer: (A)

Solution

NaOH is manufactured industrially (chlor-alkali process) by electrolysing an aqueous solution of sodium chloride: at the anode , and at the cathode, since is not discharged from aqueous solution, water is reduced instead, (equivalently $+ →
