(B) The atomic number of Nitrogen $(N)$ is $7$. The electronic configuration of $N$ is $1s^2 2s^2 2p^3$.For the $N^{+2}$ ion,two electrons are removed from the $2p$ orbital.The electronic configuration of $N^{+2}$ becomes $1s^2 2s^2 2p^1$.In the $2p^1$ orbital,there is $1$ unpaired electron.Therefore,the number of unpaired electrons is $1$.
