In One Type of Fuel Cell, Methanol CH₃OH) Enters on One

In one type of fuel cell, methanol CH₃OH) enters on one side of the unit and air enters on the other side.Both circulate past electrodes and chemically react to produce carbon dioxide and water along with electricity.Which chemical equation best represents the reaction that occurs?

A) CH₃ OH(l) $\rightarrow$ CO₂ (g) + 2 H₂ O(l)
B) 2 CH₃ OH(l) + 3 O₂ (g) $\rightarrow$ 2 CO₂ (g) + 4 H₂ O(l)
C) CH₃ OH(l) $\rightarrow$ CH₂ (g) + H₂ O(l)
D) CH₃ OH(l) +N₂(g) $\rightarrow$ CH₃(g) + NO(g)
E) CH₃ OH(l) +O₂(g) $\rightarrow$ CO₂(g) + H₂O(l)
