Solution

The correct options are
B Dilute $H_{2} S O_{4}$ with copper electrodes
C Saturated solution of potassium chloride with $P t$ electrodes
When dilute $H_{2} S O_{4}$ . is electrolyzed with copper electrodes, copper from anode is converted to $C u^{+ 2}$ . When saturated solution of $K C l$ is subjected to platinum electrodes,chlorine is liberated at the anode.
