Solution

The correct option is C $H C l O_{4}$
The acidic strength increases with the increase of +ve charge on $C l$ atom. This increased positive charge makes the molecule overall more electronegative to drag the electrons from $H$ .

So the order for acidic strength is -

Acidic strength order $- H C l O_{4} > H C l O_{3} > H C l O_{2} > H C l O$
