A student constructs a galvanic cell under standard conditions at \(298\text{ K}\) as shown in the diagram. The relevant reduction half-reactions and standard reduction potentials are given in the table below.

Half-reaction	\(E^\circ\text{ (V)}\)
\(\text{Sn}^{2+}(aq) + 2e^- \rightarrow \text{Sn}(s)\)	\(-0.14\)
\(\text{Ag}^+(aq) + e^- \rightarrow \text{Ag}(s)\)	\(+0.80\)

Which of the following correctly identifies the cathode, the direction of electron flow through the external wire, and the standard cell potential, \(E^\circ_{\text{cell}}\), when the cell operates spontaneously?
