Solution

The correct option is D 2
On heating $N a N O_{3}$ , gives sodium nitrite and oxygen.

$N a N O_{3} h e a t - - \to N a N O_{2} + \frac{1}{2} O_{2}$

The oxidation number of N in $N a N O_{3}$ is +5.

The oxidation number of N in $N a N O_{2}$ is +3.

The change in the oxidation number of N is 2.

Hence, option B is correct.
