Solution

The correct option is A CO is oxidised to $C O_{2}$ with steam in the presence of a catalyst followed by absorption of $C O_{2}$ in alkali
On the industrial scale hydrogen is prepared from water gas according to following reaction sequence
$C O + H_{2} + H_{2} O catalyst ⟶ C O_{2} + H_{2} 2 N a O H - ---- \to (alkali) N a_{2} C O_{3} + H_{2} O$
From the above it is clear that CO is first oxidised to $C O_{2}$ which is then absorbed in NaOH. So the correct answer in option (a)
