The Overall Chemical Equation Resulting from the Sum of the Following

The overall chemical equation resulting from the sum of the following three steps is
2C(s) + 2H₂O(g) $\to$ 2CO(g) + 2H₂(g)
CO(g) + H₂O(g) $\to$ CO₂(g) + H₂(g)
CO(g) + 3H₂(g) $\to$ CH₄(g) + H₂O(g)

A) 2C(s) + 2H₂O(g) $\to$ CO₂(g) + CH₄(g)
B) 2C(s) + 3H₂O(g) $\to$ CO(g) + CO₂(g) + 3H₂(g)
C) 2C(s) + H₂O(g) + H₂(g) $\to$ CO(g) + CH₄(g)
D) 2CO(g) + 2H₂(g) $\to$ CH₄(g) + CO₂(g)
E) 2C(s) + CH₄(g) + 3H₂O(g) $\to$ CO(g) + 5H₂(g)
