Water does not produce CO on reacting with:

We need to identify which substance does NOT produce CO when reacting with water.

Carbon reacts with steam at high temperatures: $$C + H_2O \rightarrow CO + H_2$$ (water gas reaction). So carbon produces CO.

Methane reacts with steam in the steam reforming reaction: $$CH_4 + H_2O \rightarrow CO + 3H_2$$. So methane produces CO.

Propane similarly undergoes steam reforming: $$C_3H_8 + 3H_2O \rightarrow 3CO + 7H_2$$. So propane produces CO.

$$CO_2$$ reacts with water to form carbonic acid: $$CO_2 + H_2O \rightarrow H_2CO_3$$. This reaction does not produce CO. There is no standard reaction between $$CO_2$$ and water that yields CO.

Therefore, water does not produce CO on reacting with $$CO_2$$, and the correct answer is option (1).
