A strip of solid copper, \(\text{Cu(s)}\), is immersed in an aqueous solution of silver nitrate, \(\text{AgNO}_3\text{(aq)}\). A single-replacement oxidation-reduction reaction occurs according to the balanced equation below:

\[ \text{Cu(s)} + 2\text{Ag}^+\text{(aq)} \rightarrow \text{Cu}^{2+}\text{(aq)} + 2\text{Ag(s)} \]

A particulate representation of a microscopic section at the solid-solution interface prior to the reaction is shown in the diagram. Solvent water molecules and spectator nitrate ions, \(\text{NO}_3^-\text{(aq)}\), are omitted for clarity.

Which of the following particulate diagrams best represents the same microscopic section after the reaction between \(\text{Cu(s)}\) and \(\text{Ag}^+\text{(aq)}\) has proceeded to completion?
