(C) The electronic configurations of the given lanthanoids are as follows: $Ce (Z=58) = [Xe] 4f^1 5d^1 6s^2$ $Nd (Z=60) = [Xe] 4f^4 6s^2$ $Sm (Z=62) = [Xe] 4f^6 6s^2$ $Eu (Z=63) = [Xe] 4f^7 6s^2$ $Gd (Z=64) = [Xe] 4f^7 5d^1 6s^2$ $Dy (Z=66) = [Xe] 4f^{10} 6s^2$ $Lu (Z=71) = [Xe] 4f^{14} 5d^1 6s^2$ Among the given options,$Gd (Z=64)$ and $Lu (Z=71)$ both possess exactly one electron in the $5d$-subshell.

Which of the following pairs of elements have one electron in the $5d$-subshell in their observed electronic configuration?
