Solution

The correct option is B Adding some Fe powder
$3 F e (s) + 4 H_{2} O (g) ⇌ {F e}_{2} O_{3} (s) + 4 H_{2} (g)$
Pressure has no effect here as $Δ n = 1 - 1 = 0$
$Δ n$ =no. of product gas moles-no. of reactant gas moles
Adding $F e$ powder can disturb the system from equilibrium as reactants concentration increases, according to Le Chatelier's principle, equilibrium shifts towards products side.
Temperature does not have any effect because it is not mentioned whether the reaction is exothermic or endothermic. $N_{2}$ does not change the equilibrium because there is no $N_{2}$ in the reaction.
