Vedclass · Answer

(C) chemical reaction will occur if a more reactive metal displaces a less reactive metal from its salt solution.According to the reactivity series,the order of reactivity is $Mg > Zn > Fe > Pb > Cu$.In option $C$,$Fe$ is more reactive than $Cu$,so $Fe$ can displace $Cu$ from $CuSO_4$ solution to form $FeSO_4$ and $Cu$.The reaction is: $Fe(s) + CuSO_4(aq) \rightarrow FeSO_4(aq) + Cu(s)$.In other options $(A, B, D)$,the metal added is less reactive than the metal present in the salt solution,so no reaction will occur.
