Solution

The correct option is D Catalyst
$\Rightarrow$ Oxidising action:
$P b S (s) + 4 H_{2} O_{2} (a q) \to P b S O_{4 (s)} + 4 H_{2} O (l)$

$\Rightarrow$ Reducing action:
$H O C l + H_{2} O_{2} \to H_{3} O^{+} C l^{-} + O_{2}$

$\Rightarrow$ In daily life it is used as a hair bleach.

$\Rightarrow$ Hydrogen peroxide is used as an antiseptic under the name of perhydrol.
