Solution

The correct option is A $P b O_{2} (s) + H_{2} O_{2} (a q) \to P b O (s) + H_{2} O (l) + O_{2} (g)$
$P b O_{2} (s) + H_{2} O_{2} (a q) \to P b O (s) + H_{2} O (l) + O_{2} (g)$

In above reaction, $H_{2} O_{2}$ acts as reducing agent because it undergoes oxidation to $O_{2}$ and it reduces the $P b O_{2}$ to $P b O$ .
