Which of the following reactions correctly represents the existence of ${\mathrm{Cl}}_2{\mathrm{O}}_6$ as $\left({\mathrm{ClO}}_2^{+}\right)\left({\mathrm{ClO}}_4^{-}\right)$

The correct reaction is,

${\mathrm{Cl}}_2{\mathrm{O}}_6+\mathrm{HF}⟶{\mathrm{FClO}}_2+{\mathrm{HClO}}_4$

This correctly represents the existence of ${\mathrm{Cl}}_2{\mathrm{O}}_6$ as $\left({\mathrm{ClO}}_2^{+}\right)\left({\mathrm{ClO}}_4^{-}\right)$
