Solution

The correct options are
B $A g N O_{3}$
C $K_{2} C r_{2} O_{4}$
D $P b C l_{2}$
Option (A),(B),(C) are correct.
Aqueous solution of $B a B r_{2}$ gives yellow ppt. with $K_{2} C r_{2} O_{4}$ , $A g N O_{3}$ and $P b C l_{2}$ .
$B a B r_{2}$ + $K_{2} C r_{2} O_{4}$ $⟶ B a C r O_{4} + 2 K B r$
$B a B r_{2}$ + $A g N O_{3}$ $⟶ A g B r + B a (N O_{3})_{2}$
$B a B r_{2}$ + $P b C l_{2}$ $⟶ P b B r_{2} + B a C l_{2}$
