For an electrochemical fdy6 7xycq:v,g6(eed0az y-a wt),hxzuya i45 uel cell in acidic conditions using methanol as the fuel source, which of the following correctly describes the ui5xytz, 4h) abalanced reactions occurring at the anode and at the cathode?
A. Anode:$CH_3OH$(g)+$H_2O$(l)→2$CO_2$(g)+6$H^{+}$(aq)+6$e^-$;Cathode:3$O_2$(g)+12H$^+$(aq)+6e$^-$→3$H_2O$(l)
B. Anode:$\frac{3}{2}$$O_2$(g)+6H$^+$(aq)+6e$^-$→3$H_2O$(l);Cathode:$CH_3OH$(g)+$H_2O$(l)→2$CO_2$(g)+6$H^{+}$(aq)+6$e^-$
C. Anode:$CH_3OH$(g)+$H_2O$(l)→2$CO_2$(g)+6$H^{+}$(aq)+6$e^-$;Cathode:$\frac{3}{2}$$O_2$(g)+6H$^+$(aq)+6e$^-$→3$H_2O$(l)
D. Anode:$CH_3OH$(g)+6$OH^-$(aq)→2$CO_2$(g)+5$H_2O$(l)+6e$^-$;Cathode:$\frac{3}{2}$$O_2$(g)+3$H_2O(l)$+6e$^-$→6OH$^-$(aq)
