The answer is B) 12.
The number of valence electrons is 7 + 4×7 +1 = 36.
If you draw a trial structure in which I is the central atom and every atom has an octet, you will have used 32 electrons.
The four extra electrons go onto the central I atom as two lone pairs.
The I atom in
This makes a total of 12 valence electrons.
