Solution

The correct options are
A $C a^{2 +} (C l O_{2}) C l^{2 -}$
B $C a^{2 +} (C l O^{+}) C l^{-}$
D $C a^{2 +} (C l_{2} O) C l^{2 -}$
The general chemical formula of bleaching powder is $C a O C l_{2}$ . In bleaching powder the chlorine atom shows $+ 1$ as well as $- 1$ oxidation state.

Thus, we can also write this formula as, $C a^{2 +} (C l O^{-}) C l^{-}$
