the salt bridge is definately there to complete the circuit. as the anode is oxidized, cations are produced. anions are therefore needed to balance out the positive charge, if not the process does not occur. ions move through the salt bridge. hence the name "salt" bridge. when atomic metal is formed at the cathode, anions are produced. cations flow to balance the negative charge through the salt bridge.

D. The electrons flow through the wire. The salt bridge keeps each side from getting too positive or negative.

B, because if the anode loses a lot of electrons, it will become extremely positive, so why would an electron leave? The salt bridge provides ions so both sides are electrically neutral.

oh come on if you draw the damn thing you can see that you get reactions on either side and to reset the reaction you need a salt bridge to help complete the circuit and have a flow of ions both ways to spurn the reaction.
