Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The metal which is having lower reduction potential is more reactive and easily dispace the metal with higher reduction potential;
$E^{0}$ for Zn is -0.76 and $E^{0}$ for copper is +0.34;
so, zinc is more reactive in comparison of copper and can easily displace copper from copper sulphate solution;
hence, both assertion and reason are correct.
