As we have learnt, 

Carius Method of detection of Oxygen -

A definite mass of an organic compound is decomposed by heating in a stream of nitrogen gas. The mixture of gaseous products containing oxygen is passed over red-hot coke when all the oxygen is converted to carbon monoxide. This mixture is passed through warm iodine pentoxide (I2O5) when carbon monoxide is oxidised to carbon dioxide producing iodine.

Thus, Iodine Pentoxide is converted to Iodine upon reaction with Carbon Monoxide.

Hence, the correct answer is Option (4)
