Solution

The correct option is D Increasing the amount of $C O$
Given,
$C O + H_{2} O (s t e a m) ⇋ C O_{2} + H_{2}$
Adding a suitable catalyst will increase the rate of the reaction but it will not increase the amount of $H_{2}$ . Adding an inert gas and decreasing the volume of the container will also have no effect on the amount of $H_{2}$ , since the volume in the reactant and product side of the equilibrium are equal.
Increasing the amount of $C O$ will shift the equilibrium towards right. That means more amount of $C O_{2}$ will be formed according to Le-Chatelier's principle.
