Solution

The correct option is D Potassium ferricyanide is reduced to potassium ferrocyanide and $H_{2} O_{2}$ is oxidised to $O_{2}$
When an alkaline solution of potassium ferricyanide is reacted with $H_{2} O_{2}$ , potassium ferricyanide is reduced to potassium ferrocyanide and $H_{2} O_{2}$ is oxidised to $O_{2}$ .
$2 K_{3} [F e (C N)_{6}] + 2 K O H \to 2 K_{4} [F e (C N)_{6}] + H_{2} O + [O]$
$H_{2} O_{2} + [O] \to H 2 O + O_{2}$
