Answer:

D. CH₄(g) + H₂O(g) → CO(g) + 3H₂(g)

Explanation:

A rule of thumb is that there's an increase in entropy if there are more molecules in the products than in the reactants when there's no state change. The only given option where that takes place is option D., as there are two molecules in the reactants and 4 (1 of CO and 3 of H₂) in the products.
