Vedclass · Answer

(D) displacement reaction occurs when a more reactive metal displaces a less reactive metal from its salt solution.According to the reactivity series,copper $(Cu)$ is more reactive than silver $(Ag)$.Therefore,copper can displace silver from silver nitrate $(AgNO_{3})$ solution.The chemical reaction is: $Cu(s) + 2AgNO_{3}(aq) \rightarrow Cu(NO_{3})_{2}(aq) + 2Ag(s)$.In the other options,the metal added is less reactive than the metal present in the salt solution,so no displacement reaction will occur.
