\mathrm{ClO_3^-}+6\,\mathrm{I^-}+6\,\mathrm{H^+}\rightarrow\mathrm{Cl^-}+3\,\mathrm{I_2}+3\,\mathrm{H_2O}

. Which of the following correctly identifies the species that is oxidized and the overall reaction type? (a)

\mathrm{ClO_3^-}

is oxidized; the reaction is oxidation–reduction. (b)

\mathrm{I^-}

is oxidized; the reaction is oxidation–reduction. (c)

\mathrm{I^-}

is reduced; the reaction is oxidation–reduction. (d)

\mathrm{ClO_3^-}

is reduced; the reaction is acid–base.
