Solution

The correct option is C $P b (N O_{3})_{2}$
$2 K I O_{3} + P b (N O_{3})_{2} ⟶ P b (I O_{3})_{2} + 2 K N O_{3}$
$0.8 \times 15$ $35 \times 0.15$
$= 12$ $= 5.25$
$1$ mol of $P b (N O_{3})_{2}$ reacts with $2$ mol of $K I O_{3}$
$5.25$ mmol of $P b (N O_{3})_{2}$ reacts $= 2 \times 5.25 = 10.5$ mmol
The number of mmol of $K I O_{3}$ left $= 12 - 10.5 = 1.5$

Hence, $P b (N O_{3})_{2}$ is the limiting reactant.
