💡 Solution & Explanation

Sodium is indeed discharged preferentially at a mercury cathode to form sodium amalgam, primarily due to the very high overvoltage of hydrogen on mercury. Thus, Statement I is true. However, Na^+ is an exceptionally weak oxidizing agent (and not a reducing agent at all). Thus, Statement II is completely false. Therefore, correct answer is C.
