I said D, the most reactive element will oxidise (go into solution) and is the anode
1. x<Pb
2. Pb<y
3. Pb<z
4. y<z
You need to use you potential values for the last one to see that they both use Pb, and so z must have a higher voltage potential or something and so
put them together you get x<Pb<y<z
That's how I did it anyway, don't know if it is 100% right
