Using the Following Data,calculate the Standard Enthalpy of Reaction for the Coal

Using the following data,calculate the standard enthalpy of reaction for the coal gasification process 2C(s) + 2H₂O(g) → CH₄(g) + CO₂(g) .
C(s) + H₂O(g) → CO(g) + H₂(g) ; ΔH° = +131.3 kJ
CO(g) + H₂O(g) → CO₂(g) + H₂(g) ; ΔH° = -41.2 kJ
CO(g) + 3H₂(g) → CH₄(g) + H₂O(g) ; ΔH° = -206.1 kJ

A) -116.0 kJ
B) 378.6 kJ
C) +15.3 kJ
D) -157.2 kJ
E) -378.6 kJ
