Solution

The correct option is A
ZnCl₂

The given equations are self explanatory

$Z n C l_{2} + N a O H \to Z n (O H)_{2} N a_{2} Z n O_{2} (s o l u b l e)$

$F e C l_{3} + N a O H \to F e (O H)_{3}$ $(b r o w n p p t)$

$C r C l_{3} + N a O H \to C r (O H)_{3} (g r e e n p p t)$

$C u S O_{4} + N a O H \to C u (O H)_{2} (b l u e p p t)$
