Solution

The correct option is C $N O_{3}^{-}$
A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in solution as spectator ion.
$⟶$ Ions that are not involved in the actual chemical reaction are called spectator ions.
$⟶$ Net ionic equation of given reaction is
$P b^{+ 2} + 2 I^{-} ⟶ P b I_{2}$ It shows only the ions which involves in the chemical reaction,
Spectator ions:- $K^{+}$ and ${N O_{3}}^{-}$ .
