The relationship between a
cathode and an anode involves electrons. The answer is letter B. An example of
this is reaction that takes place in an electrolytic cell. It has a cathode compartment,
an anode compartment and a salt bridge that divides the compartment. The movement
of electrons is from the cathode to the anode. The cathode serves as the
positive terminal and the anode as the negative terminal. The flow of electrons
is from the cathode to the anode.
