Solution

The correct option is A $3 F e + 4 H_{2} O \to F e_{3} O_{4} + 4 H_{2}$
In the above example, to balance given reaction number of atoms added on reactant and product side is :
$F e =$ 3 (Reactant side)
$H_{2} O = 4$ (Reactant side)
$H_{2} = 4$ (Product side)
$3 F e + 4 H_{2} O \to F e_{3} O_{4} + 4 H_{2}$
