Solution

The correct option is A ${Fe}_{2} O_{3}$
Hydrogen is commercially synthesised from water gas $(CO + H_{2})$ by bosch process. Water gas is obtained by passing steam over red hot coke.

$C (s) + H_{2} O (steam) 1000 ° C - --- \to CO (g) + H_{2} (g)$

This water gas is then made to react with excess steam to obtain $H_{2}$ gas along with ${CO}_{2}$ . This reaction is called water gas shift reaction.

$CO (g) + H_{2} (g) + H_{2} O (steam) 450 ° C - -- \to {Fe}_{2} O_{3} {CO}_{2} + 2 H_{2}$
In this reaction, $F e_{2} O_{3}$ is used as a catalyst.
