Study the Assertion and Reason and choose the correct option.
If a solution contains both and ions, the ions are reduced first at cathode.
Assertion: If a solution contains both $\text{H}^+$ and $\text{Na}^+$ ions, the $\text{H}^+$ ions are reduced first at cathode.
Reason: Cations with higher $E^\circ$ value are reduced first at cathode.
- (a)Both Assertion and Reason are true, and Reason is the correct explanation for Assertion.
- (b)Both Assertion and Reason are true, but Reason is not the correct explanation for Assertion.
- (c)Assertion is true but Reason is false.
- (d)Assertion is false but Reason is true.
