Solution

The correct option is B Positively and negatively charges electrodes
In both kinds of electrochemical cells, the anode is the electrode at which the oxidation half-reaction occurs, and the cathode is the electrode at which the reduction half-reaction occurs. The anode is considered positive and the cathode is considered negative.
Hence, the correct option is $B$
