If the Assertion is correct but Reason is incorrect.

(C) Magnesium $(Mg)$ continues to burn in nitric oxide $(NO)$ because the heat evolved during the combustion of $Mg$ is sufficient to decompose $NO$ into $N_2$ and $O_2$.The reaction is: $2Mg + 2NO \rightarrow 2MgO + N_2$.Since the heat evolved decomposes $NO$,the Reason provided is incorrect.
