Best answer

(C) (i), (ii) and (iv)

In the given reaction, there is addition of oxygen to iron metal and it is oxidised. Also, there is removal of hydrogen from the water and thus, water is reduced. A substance which causes oxidation of other chemical species in a chemical reaction and itself undergoes reduction, is known as an oxidising agent. Thus, in given reaction, water is acting as an oxidising agent.
