The correct option is "only one" because, while the functions and organizational structures in each row are partially aligned, there is an error in the first row's alignment. The Directorate of Enforcement primarily functions under the Ministry of Finance, specifically pertaining to economic offenses, rather than the Ministry of Home Affairs. The second and third rows are accurately matched to their respective ministries and functions, indicating that only one of the three descriptions is correct in its entirety. This analysis is significant for the UPSC Prelims as it underscores the importance of understanding the specific roles and organizational hierarchy of government bodies, which is essential for effective governance and policy implementation, a key area of focus in examination syllabi.
