(B) The atomic number of $Zn$ is $30$. The electronic configuration of $Zn$ is $[Ar] 3d^{10} 4s^{2}$.For $Zn^{+}$ ion,one electron is removed from the $4s$ orbital,so the configuration becomes $[Ar] 3d^{10} 4s^{1}$.The outermost electron is in the $4s$ subshell.For an $s$-orbital,the azimuthal quantum number $l = 0$.The magnetic quantum number $m$ ranges from $-l$ to $+l$,so for $l = 0$,$m = 0$.
