Statement $I$: $\mathrm{PF}_5$ and $\mathrm{BrF}_5$ both exhibit $\mathrm{sp}^3 \mathrm{~d}$ hybridisation.
Statement $II$: Both $\mathrm{SF}_6$ and $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ exhibit $\mathrm{sp}^3 \mathrm{~d}^2$ hybridisation.
In the light of the above statements, choose the correct answer from the options given below:

(Given : $h =6.63 \times 10^{-34} \,Js , N _{ A }=6.02 \times 10^{23} \,mol ^{-1}$, $c =3 \times 10^{8}\, ms ^{-1}$ )
$Gas$ $(A)$ bums with a blue flame and is oxidised to $gas$ $(B)$,
$Gas\left( A \right) + C{l_2} \to \left( D \right)\xrightarrow{{N{H_3},\Delta }}\left( E \right)$.
$A,B, C$ and $E$ are
