Answer is: A. adding heat to the product mixture.

Balanced chemical reaction:

CO (g) + 3H₂ (g) ⇄ CH₄ (g) + H₂O (g); ΔH = - 206.1 kJ.

This reaction is exothermic, which means that heat is released.

According to Le Chatelier's principle when the reaction is exothermic heat is included as a product and when the temperature increased, the heat of the system increase, so the system consume some of that heat by shifting the equilibrium to the left.
