Solution

The correct option is D $K N O_{3}$
Option (D) is correct.
$K N O_{3}$ on heating does not produces $N O_{2}$ while rest of them gives $N O_{2}$ .
Potassium nitrate decomposes on heating, producing potassium oxide and gaseous nitrogen and oxygen.
$4 K N O_{3} \to 2 K_{2} O + 2 N_{2} + 5 O_{2}$
