(C) The atomic number of $Fe$ is $26$. The electronic configuration of $Fe$ is $1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6$. Grouping the electrons by principal quantum number $(n)$: $n=1$: $2$ electrons $(1s^2)$ $n=2$: $8$ electrons $(2s^2 2p^6)$ $n=3$: $14$ electrons $(3s^2 3p^6 3d^6)$ $n=4$: $2$ electrons $(4s^2)$ Thus,the arrangement is $2, 8, 14, 2$.

$Fe$ (atomic number $= 26$) atom has the electronic arrangement:
