Solution

The correct option is D $H O C l O_{2}$
$H C l$ , known as hydrochloric acid and is not an oxoacid but haloacid. All oxoacids have the acidic hydrogen bound to an oxygen atom, in $H C l$ the hydrogen is bound to the chlorine atom making it a Lewis acid.
Except $H C l$ , all other $H O C l, H O C l O, H O C l O_{2}$ are oxa-acids.
