Pick up the false statement(s):
(a) The net chemical change in a galvanic cell reaction is always redox reactions.
(b) In a galvanic cell made of copper and cadmium electrodes, cadmium electrode may act as anode.
(c) Standard potential increases with increasing concentration of the electrolyte.
(d) Calomel electrode is a reference electrode having \( 0.00 \) volt potential.
