Solution

The correct option is D $15^{t h}$ group and $6^{t h}$ period
$_{88}^{226} R a {- α ⟶}_{86} R n - α ⟶ R a A - β ⟶ R a B - α ⟶ R a C$

$_{88}^{226} R a {- α ⟶}_{86} R n {- α ⟶}_{84} R a A {- β ⟶}_{85} R a B {- α ⟶}_{83} R a C$

Element with atomic number 83 lies in $15^{t h}$ group and $6^{t h}$ period.
