D(i) Assertion:If a solution contains both H⁺ and Na⁺ ions, the H⁺ ions are reduced first at cathode.

Reason: Cations with higher E⁰ 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.
