The correct answer is D: Both A and B (South Sudan and Somalia). According to Transparency International's 2020 Corruption Perception Index (CPI), South Sudan and Somalia were indeed among the countries perceived to be the most corrupt globally. Both nations scored 12 points out of 100, placing them at the very bottom of the index. This indicates a severe perception of public sector corruption, often linked to political instability, weak governance, and a lack of accountability within their respective governments and institutions. The CPI is a crucial indicator that reflects expert and business people's perceptions of corruption, and these countries consistently feature at the lowest ranks due to systemic issues.
- A: South Sudan is incorrect as a standalone answer because while it was one of the most corrupt, it was not the sole country at the absolute bottom when considering all options.
- B: Somalia is also incorrect as a standalone answer for the same reason. It shared the lowest rank with South Sudan in the 2020 index.
- C: Syria was also highly corrupt in 2020, scoring 14 points, which placed it only slightly above South Sudan and Somalia. However, the option D: Both A and B more accurately captures the countries that were tied for the lowest rank, making it the most comprehensive and correct choice given the multiple-choice format.
