For an electrochemical fuel c n.lcjik ev3(31oth1y ell in accf4g *f8ocfg-de 4hn ;idic conditions using methanol as the fuel source, which of the fo ghfof-cc; *d44ngef8 llowing correctly describes the balanced 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)
