पर्याय

• (i), (ii) and (iii)

•  (iii) and (iv)

• (i), (ii) and (iv)

• (ii) and (iv)

Answer 1

 (i), (ii) and (iv)

Explanation - 

In the following reaction, `3"Fe"("s") + 4"H"_2"O"("g") -> "Fe"_3"O"_4("s") + 4"H"_2("g")`

As the addition of oxygen is called oxidation and removal of oxygen is known as reduction so, Fe is getting oxidised to Fe₃O₄ , at the same time H₂O is getting reduced to H₂.
In a redox reaction, the reactant causing the oxidation of other reactant is called as an oxidising agent since H₂O is causing the oxidation of Fe, therefore H₂O is the oxidising agent.

Hence, the correct answer is option 3.
