What are the appropriate balanced half-reactions for the following reaction, which is carried out in an acidic solution: I− + IO3− arrow I2 ?

I− arrow I2 (oxidized) and IO3 arrow I2 (reduced)

IO3 arrow I2 (oxidized) and I− arrow I2 (reduced)

2 I− arrow I2 + 2 e− (oxidized) and 2 IO3− + 2 e− arrow I2 (reduced)

2 I− arrow I2 + 2 e− (oxidized) and 2 IO3− + 10 e− arrow I2 (reduced)
