Chlorine undergoes disproportionation reaction in alkaline medium. It is the simultaneous oxidation-reduction. Chlorine is simultaneously reduced to chloride ion ${Cl}^{-}$ and is oxidised to ${ClO}^{-}$ ion. Halogens (e.g. Cl) have a strong tendency to accept electrons, so they act as strong oxidising agents.

The reaction is as follows,

$\Rightarrow Cl_{2} - 2 O H^{-} ⟶ Cl^{-} + ClO^{-} + H_{2} O$

Hence the values of a,b,c,d are $1, 2, 1, 1 .$
