Solution

The correct option is B $C O (g) + 2 H_{2} (g) C o b a l t - ---- \to C a t a l y s t 2 C O + 5 H_{2}$
Water gas is a mixture of carbon monoxide $(C O)$ and hydrogen $(H_{2})$ gases. It is used in synthesis of methanol:

$C O (g) + 2 H_{2} (g) C o b a l t - ---- \to C a t a l y s t 2 C O + 5 H_{2}$

Hence, option (D) is correct.
