Solution

The correct options are
B Calcium hydroxide precipitates near cathode on prolonged hydrolysis.
C Chlorine is liberated on anode
During electrolysis of aqueous $C a C l_{2}$
We have,
At anode: $2 C l^{-} \to C l_{2} + 2 e^{-}$
At anode: $2 H^{+} + 2 e^{-} \to H_{2}$
Electrolyte = $C a^{2 +} + O H^{-}$
