Answer

To determine the overall reaction in the galvanic cell, we need to look for a redox process involving silver (Ag) and copper (Cu). The correct reaction must balance both the oxidation and reduction half-reactions. Upon reviewing the answer choices, option C fits this requirement:

ightarrow ext{2Ag (s)} + ext{Cu}^{2+} ext{(aq)}$$ This indicates that silver ions are reduced to solid silver while solid copper is oxidized to copper ions.
