Solution

The correct option is C lead [IV] oxide
Explanation :-
In $H C l$ , the chlorine atom present with $- 1$ oxidation state and $C l_{2}$ has zero oxidation state. It means chlorine undergoes reduction that is only possible in the presence of a strong oxidizing agent.

$P b O_{2} s t r o n g o x i d i z i n g a g e n t (P b i n + 4 s t a t e) + 4 H C l \to P b C l_{2} + C l_{2} + 2 H_{2} O$
