Solution
If Assertion is INCORRECT but Reason is CORRECT.
Explanation:
Copper cannot displace zinc from the solution of zinc sulphate because copper is below zinc in the electrochemical series. The displacement reaction occurs only when a metal is above another metal in the series, as it has a higher reducing power. Hence, the assertion is incorrect, but the reason (that copper is below zinc in the electrochemical series) is correct.
