Solution

The correct option is C $P b C r O_{4}$

$C r C l_{3} + 3 N a O H \to \begin{matrix} C r (O H)_{3} (A) \end{matrix} + 3 N a C l$

$C r (O H)_{3} + N a_{2} O_{2} + H_{2} O \to \begin{matrix} N a_{2} C r O_{4} (B) y e l l o w \end{matrix}$

$N a_{2} C r O_{4} + C H_{3} C O O)_{2} P b \to \begin{matrix} P b C r O_{4} ↓ (C) y e l l o w p p t . \end{matrix}$
