Solution

The correct option is A oxidising agent in both (i) and (ii)
GIven:
(i) H2O2H2O+[O]
Here, the oxidation state of O changes from 1 to 2 and 0.
(ii) H2O2+2II2+2OH
Here, the oxidation state of I changes from 1 to 0. Hence, H2O2 oxidises iodine while itself gets reduced.
Hence, H2O2 acts as oxidising agent in both the above reactions.
