Solution

The correct option is D $x \to s; y \to a q$
$P b (N O_{3})_{2} (a q) + 2 K I (a q) \to P b I_{2} (s) + 2 K N O_{3} (a q)$
Above reaction is a precipitation and a double displacement reaction in which solid precipitates of lead iodide $(P b I_{2})$ are formed .Therefore $x$ represents solid $(s)$ form of lead iodide and $y$ represents aqueous $(a q)$ form of potassium nitrate.
