    The correct answer is option (b) Chlor-alkali process

    Information booster :

    The overall reaction for the chlor-alkali process is:

    2NaCl(aq)+2H2O(l)2NaOH(aq)+Cl2(g)+H2(g)2NaCl (aq) + 2H_2O (l) \rightarrow 2NaOH (aq) + Cl_2 (g) + H_2 (g)

    Sodium hydroxide (NaOH) is primarily prepared through the chlor-alkali process, which involves the electrolysis of brine (a concentrated solution of sodium chloride, NaCl).
