Correct Answer - A
(A) `CuSO_(4)rarrCu+O_(2):CuCl_(2)rarrCu+I_(2)`
(B) `KClrarrH_(2)+Cl_(2):KIrarrH_(2)+I_(2)`
(C) `AgNO_(3)rarrAG+O_(2),:NaClrarrH_(2)+Cl_(2)`
(D) `KClrarrH_(2)+Cl_(2):NaClrarrH_(2)+Cl_(2)`
(E) `CuBrrarrCu+Br_(2):CuSO_(4)rarrCu+O_(2)`
Thus KCl and NaCl solution give the same products at anode and cathode.
