Their $d-$orbitals are completely filled.

(A) The correct answer is $(A)$. The elements $Zn,$ $Cd,$ and $Hg$ have the general electronic configuration $(n-1)d^{10}ns^2$. Since their $d-$orbitals are completely filled in their ground state as well as in their common oxidation states,they do not exhibit the characteristic properties of transition elements,such as the formation of coloured ions or variable oxidation states.
