(D) The electronic configuration of the element is $2, 8$. This means the element has a total of $10$ electrons,which corresponds to the atomic number $10$. The element with atomic number $10$ is Neon $(Ne)$. In the Modern Periodic Table,elements with a completely filled outermost shell (octet) are placed in Group $18$,which consists of noble gases. Since the valence shell of this element is full ($8$ electrons),it belongs to Group $18$.
