Solution

The correct option is D ${F e}_{2} O_{3} + {C r}_{2} O_{3}$
Water gas (1:1 volume ratio of CO and hydrogen) 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 $440 - 550^{o} C$ .

$C O + H_{2} + H_{2} O F e_{2} O_{3} + C r_{2} O_{3} - -------- \to 440 - 550^{o} C C O_{2} ↑ + 2 H_{2}$
