(A) An oxidising agent is a substance that gains electrons and undergoes reduction,meaning its oxidation state must be able to decrease.In $I^{-}$,the iodine atom is in its lowest possible oxidation state of $-1$. Therefore,it cannot lose electrons to be reduced further; it can only act as a reducing agent by losing electrons to become $I_2$.Conversely,$S_{(s)}$,$NO_3^{-}$,and $Cr_2O_7^{2-}$ contain elements in oxidation states that can be reduced further.
