(B) The general electronic configuration of $d$-block elements is $(n-1)d^{1-10}ns^{1-2}$.$(i)$ $1s^2 2s^2 2p^6 3s^2$ is Magnesium $(Mg)$,which is an $s$-block element.$(ii)$ $1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10} 4s^2$ is Zinc $(Zn)$,which is a $d$-block element.$(iii)$ $1s^2 2s^2 2p^5$ is Fluorine $(F)$,which is a $p$-block element.$(iv)$ $1s^2 2s^2 2p^6 3s^2 3p^3$ is Phosphorus $(P)$,which is a $p$-block element.Therefore,only configuration $(ii)$ belongs to the $d$-block elements.

Which of the following electronic configurations belongs to the $d$-block elements?
