Which of these can be deduced according to this electrochemical cell?

A. In the cell, zinc oxidizes magnesium and causes it to lose electrons. Magnesium must be less chemically active than zinc, and an oxidizing agent.
B. In the cell, magnesium loses electrons and is reduced. The reduction half-reaction is: Mg2+(aq) -> Mg(2)+2e-
C. In the cell, magnesium oxidizes zinc and causes it to lose electrons. In the activity series, Mg must be higher up than ZN.
D. In the cell, electrons are generated by reduction at the zinc electrode. The electrons then flow through the wire to the magnesium electrode.

I couldn't get that image.
