Solution

The correct option is A IO3
Oxidaiton of I with KMnO4 in alkaline solution is given by
Reaction: 6MnO4+I+6OHIO3+6MnO24+3H2O
Here the oxidation state of Mn reduced from +7 to +6 and the oxidation state of I oxidised from -1 to +5.
6e is involved in the reaction.
Oxidation product form is IO3.
Hence, option A is correct.
