Solution

The correct option is B ${Fe}_{3} O_{4} (s)$
Fe reacts with steam to produce $F e_{3} O_{4}$ along with the evolution of hydrogen gas. This is a reversible reaction since the $H_{2}$ gas released can react with $F e_{3} O_{4}$ to give back $F e$ and $H_{2} O$ .

$3 Fe (s) + 4 H_{2} O (steam) ⇌ 4 H_{2} (g) + {Fe}_{3} O_{4} (s)$
