The President of which country was impeached after he imposed martial law on December 2024?

South Korea

The correct answer is option 2: South Korea

In December 2024, South Korean President Yoon Suk Yeol declared martial law, citing alleged "anti-state activities" by the opposition-controlled National Assembly. This action led to significant political turmoil and public protests. On December 14, 2024, the National Assembly voted to impeach Yoon. The Constitutional Court upheld this decision on April 4, 2025, officially removing him from office. ​
