A galvanic cell is constructed at \(298\text{ K}\) using zinc and copper half-cells connected by an external wire and a salt bridge containing \(\text{KNO}_3\text{(aq)}\), as shown in the diagram. The standard reduction potentials for the two half-reactions are given below.

\[\text{Zn}^{2+}\text{(aq)} + 2\,e^- \rightarrow \text{Zn(s)} \quad E^\circ = -0.76\text{ V}\]
\[\text{Cu}^{2+}\text{(aq)} + 2\,e^- \rightarrow \text{Cu(s)} \quad E^\circ = +0.34\text{ V}\]

Which of the following correctly describes the direction of electron flow in the external circuit and the movement of ions from the salt bridge as the cell operates spontaneously?
