(B) The element $E$ with configuration $4s^2 4p^1$ is Gallium $(Ga)$,which belongs to period $4$ and group $13$.Diagonal relationship exists between elements of period $2$ and $3$,and period $3$ and $4$. However,the question asks for an element in period $5$ placed diagonally to $E$ $(Ga)$.In the periodic table,the element placed diagonally to $Ga$ $(Z=31)$ in the next period (period $5$) is Tin ($Sn$,$Z=50$).$Sn$ is a group $14$ element in period $5$.The electronic configuration of $Sn$ $(Z=50)$ is $[Kr] 4d^{10} 5s^2 5p^2$.
