Solution

The correct option is A No reaction will occur
Copper cannot displace zinc from $Z n S O_{4}$ .
Hence, no reaction will occur.
Note: The standard reduction potential for $C u^{2 +} | C u$ is greater than that for $Z n^{2 +} | Z n$ .
Hence, Zn is better reducing agent than Cu. Hence, Zn can displace Cu from copper sulphate solution.
