(B) The atomic number of $Fe$ is $26$. The electronic configuration of $Fe$ is $[Ar] 3d^6 4s^2$.For $Fe^{+3}$ ion,three electrons are removed (two from $4s$ and one from $3d$),resulting in the configuration $[Ar] 3d^5$.In the $3d^5$ subshell,there are $5$ orbitals,each containing one electron according to Hund's rule.Therefore,the number of unpaired electrons in $Fe^{+3}$ is $5$.

Number of unpaired electrons in $Fe^{+3}$ $(Z = 26)$ is
