I would pick A.
B no, Mg reacts with H2O.
C no, It's Ag^+, not Ag^2+
D no, there is no Ag^2+ swolid
E no, should be Zn2+(aq)|Zn(s)
Which is a possible electrochemical cell, shown in correct notation?
A. Cd(s) | Cd2+(aq) || Cu2+(aq) | Cu(s)
B. Mg(aq) | Mg2+(aq) || Pb2+(aq) | Pb(aq)
C. Ag(s) | Ag2+(aq) || Pb3+(aq), Pb2+(aq) | Pt(s)
D. Ag2+(s) | Ag2+(aq) || Pt(s) | Pb3+(aq), Pb2+(aq)
E. Fe(s) | Fe3+(aq) || Zn(s) | Zn2+(aq)
