(B) The reaction occurring is: $2Ag^{+}(aq) + Cu(s) 	o Cu^{2+}(aq) + 2Ag(s)$.Since the standard reduction potential of silver $(E^o_{Ag^{+}/Ag} = +0.80 \ V)$ is higher than that of copper $(E^o_{Cu^{2+}/Cu} = +0.34 \ V)$,copper acts as the reducing agent and undergoes oxidation to form $Cu^{2+}$ ions.The blue colour of the solution is due to the presence of hydrated $Cu^{2+}$ ions.

When a piece of copper wire is dipped in $AgNO_3$ solution,the colour of the solution turns blue due to
