Solution

The correct option is D
Double displacement

$P b (N O_{3})_{2} (a q) + 2 K C l (a q) \to 2 K N O_{3} (a q) + P b C l_{2} (s)$

In the above reaction, $P b^{2 +}$ from $P b (N O_{3})_{2}$ displaces $K^{+}$ from KCl and forms insoluble solid $P b C l_{2}$ . Similarly, $K^{+}$ from KCl displaces $P b^{2 +}$ from $P b (N O_{3})_{2}$ to form $K N O_{3}$ solution. The ions (Cations) are exchanged between the reactants.Hence this reaction is called double displacement reaction.

General representation: $A B + C D \to A D + C B$
