How do I explain the answer please?

#1, Fe(s) is on the left, so it's anode; Pt(s) is on the right, it's a cathode...so the rxn should be D. #2: B because Fe is gaining electrons, making it a reduction=cathode.

no, there's Fe in D for the first question..Fe(s)+8H+(aq)+MnO4–(aq)+Pt2+(aq)==> Mn2+(aq)+4H2O(l)+Fe2+(aq)+Pt(s)

Pt is functioning as a cathode - D shows that Pt is cathode and Fe as anode. I don't understand why H+ and water are in the reaction so my answers 1)D 2)B
