Best answer
Right answer is (c) Chromium

To explain: Desorption is used in the manufacture of chlorides. Chromium has the capacity to renew the chlorates (which will convert to chlorides) from the acidified solution formed during the reaction. Thus it also promotes the rate of reaction by achieving the equilibrium state.
