Assertion: For a cell reaction `Zn_((s))+Cu_((aq))^(2+)toZn_((aq))^(2+)+Cu_((s))`, at the equilibrium voltmeter gives zero reading.
Reason: At the equilibrium, there is no change in the concentration of `Cu^(2+) and Zn^(2+)` ions.

A

if both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false

D
