(B) The electronic configuration of $Fe$ $(Z=26)$ is $[Ar] 3d^6 4s^2$. For $Fe^{2+}$ ion,the configuration is $[Ar] 3d^6$. In the $3d^6$ configuration,there are $4$ unpaired electrons $(n=4)$. The spin-only magnetic moment is calculated using the formula $\mu = \sqrt{n(n+2)} \ BM$. Substituting $n=4$,we get $\mu = \sqrt{4(4+2)} = \sqrt{24} \approx 4.90 \ BM$.
