The standard reduction potentials of \(\mathrm{Zn}\) and \(\mathrm{Ag}\) in water at \(298 \mathrm{~K}\) are,
\(\begin{aligned}
\mathrm{Zn}^{2+}+2 e^{-} \rightleftharpoons \mathrm{Zn}, & E^{\circ}=-0.76 \mathrm{~V} \\
\text { and } \quad \mathrm{Ag}^{+}+e^{-} \rightleftharpoons \mathrm{Ag} ; & E^{\circ}=+0.80 \mathrm{~V}.
\end{aligned}\)
Which of the following reactions take place?

1. A \(\mathrm{Zn}^{2+}(a q)+2 \mathrm{Ag}(s) \longrightarrow 2 \mathrm{Ag}^{+}(a q)+\mathrm{Zn}(s)\)
2. B \(\mathrm{Zn}(s)+2 \mathrm{Ag}^{+}(a q) \longrightarrow \mathrm{Zn}^{2+}(a q)+2 \mathrm{Ag}(s)\)
3. C \(\mathrm{Zn}^{2+}(a q)+\mathrm{Ag}^{+}(a q) \longrightarrow \mathrm{Zn}(s)+\mathrm{Ag}(s)\)
4. D \(\mathrm{Zn}(s)+\mathrm{Ag}(s) \longrightarrow \mathrm{Zn}^{2+}(a q)+\mathrm{Ag}^{+}(a q)\)
