Does pH have an effect on the cell potential (Ecell) for the following oxidation-reduction reaction?

5Fe^2+(aq) + MnO4^-(aq) + 8H^+(aq) ---> 5Fe^3+(aq) + Mn^2+(aq) + 4H20(l)

A) No, because (Ecell) values for redox reactions depend on concentrations and temperatures but not on pH.

B) Yes, because (Ecell) values for all redox reactions depend on the pH.

C) No, becaue (Ecell) values for redox reactions do not depend on the pH.

D) Yes, because (Ecell) values for redox reactions involving the hydromium ion depend on the pH.
