Correct Answer: Option C
Explanation

Sodium (Na\(^+\)) and potassium (K\(^+\)) are cations, meaning they have already lost an electron to achieve a stable noble gas configuration. Because they are positively charged, they have a tendency to accept electrons to return to their neutral elemental state (Na or K), a process called reduction.

Conversely, option A, which is the tendency to give electrons describes the neutral atoms (Na and K) which are strong reducing agents that readily lose their single valence electron. Once they become Na\(^+\) and K\(^+\) ions, they have a stable octet and do not tend to lose further electrons.

The correct answer is option C.
