Solution

The correct options are
C
$H I O_{4}$

D
$H_{5} I O_{6}$

Mole ratioof iodine : oxygen $= \frac{254}{127} : \frac{112}{16} = 2 : 7$
The oxide is $I_{2} O_{7}$ .
When dissoved in water it can produce $H I O_{4}$ or $H_{5} I O_{6}$
$I_{2} O_{7} + H_{2} O \to 2 H I O_{4}$
$I_{2} O_{7} + 5 H_{2} O \to 2 H_{5} I O_{6}$
