KCl can make precipitate with AgNO3, Pb(NO3)2 so can’t be used along these electrolytes

Q. $K Cl$ can be used in salt bridge as an electrolyte in which of the following cells?

$Z n ∣ Z n C l_{2} ∣∣ A g N O_{3} ∣ A g$

$P b ∣ P b (N O_{3})_{2} ∣∣ C u (N O_{3})_{2} ∣ C u$

$C u ∣ C u S O_{4} ∣∣ A u C l_{3} ∣ A u$

$F e ∣ F e S O_{4} ∣∣ P b (N O_{3})_{2} ∣ P b$

$K Cl$ can make precipitate with $A g N O_{3}, P b (N O_{3})_{2}$ so can’t be used along these electrolytes
