The Following Set of Redox Reactions Takes Place as Shown

The following set of redox reactions takes place as shown. If you had two containers filled with the ion solution described above with a wire connecting a piece of iron (in container A) and a piece of copper (in container B) and a salt-bridge connecting the two containers, which way do the electrons flow?

A) There is no continuous flow of electrons.
B) The electrons flow from container A to container B.
C) The electrons flow from container B to container A.
D) The electrons flow back and forth between the two containers.
E) The electrons only move in the containers they originate in.
