Solution

The correct option is D $Z n O + C r_{2} O_{3}$
Water-gas is a mixture of carbon monoxide and hydrogen gas. It is also known as synthesis gas.

It is widely used to produce methanol by the below-mentioned reaction:
$C O + 2 H_{2} \to C H_{3} O H$

This reaction requires $Z n O$ and $C r_{2} O_{3}$ as catalyst which produces methanol with high selectivity $(> 99.8 %)$ .

Hence, option A is correct.
