Solution

The correct option is D Double Displacement Reaction
Double displacement reaction is a reaction where two compounds react by an exchange of ions to form two new compounds. Lead iodide is an insoluble compound. It forms precipitate in this reaction which is yellow in colour.

The reaction is $2 K I (a q) + P b (N O_{3})_{2} (a q) \to P b I_{2} ↓ 2 K N O_{3} (a q)$ which is a double displacement reaction.
