Answer:
D) a salt bridge
Explanation:
A salt bridge completes an electrochemical cell. A salt bridge maintains charge balance in the two half cells. If the salt bridge is not present, the anode compartment becomes positively charged while the cathode compartment becomes negatively charged hence the reaction reaches equilibrium and comes to a halt quickly.
