Solution

The correct option is D Water gas
In Bosch's process, water gas $(1 : 1$ volume ratio of $C O$ and $H_{2}$ $)$ is mixed with steam and passed over $F e_{2} O_{3}$ catalyst with promoter $C r_{2} O_{3}, T h O_{2}$ etc. at $440 - 550^{o} C$ .
The reaction is as follows:
$C O + H_{2} + H_{2} O F e_{2} O_{3} + C r_{2} O_{3} - -------- \to 440 - 550^{o} C C O_{2} ↑ + 2 H_{2}$
