(D) According to the Group Displacement Law,when an element emits an $\alpha$-particle $(_{2}He^{4})$,its atomic number decreases by $2$ and it moves two groups to the left in the periodic table.Since $Pb$ (lead) belongs to group $IV A$,the parent element $Po$ (polonium) must be located two groups to the right of $Pb$.Therefore,the group of $Po = IV A + 2 = VI A$.
