Explanation:

- The phrase "one who embraces voluntary death for the sake of one's country" describes someone who sacrifices their life with the intent of benefiting their nation or cause.

- Option 1: Fanatic

- A fanatic is someone with extreme, uncritical enthusiasm or zeal, often for religious or political causes. It doesn't specifically refer to dying for one's country.

- Option 2: Martyr

- A martyr is someone who dies voluntarily for their religion, country, or a cause they believe in. This matches the description provided.

- Option 3: Patriot

- A patriot is someone who loves and supports their country. It does not inherently involve dying for it, so this doesn't completely fit.

- Option 4: Diplomat

- A diplomat engages in negotiations and maintains relations between countries. This term is unrelated to the concept of voluntary death for a country.

Based on the definitions, Option 2: Martyr is indeed the correct choice. ""
