Solution

The correct option is C The bond between I and O should be represented with a single line
In a Lewis dot structure, a single bond has to be drawn from the central atom to the other atom for each shared pair of electron
Net charge on the compound should always be outside the brackets
Number of electrons available with oxygen is 8 which satisfies oxygen according to the octet rule
Total number of electrons on IO =7+6+1=6 which is equal to that in the Lewis structure
Hence, A is the correct answer
