In January 2020, the administration of which of the following Union Territories has been merged together?

In January 2020, the administration of the Union Territories of Dadra and Nagar Haveli and Daman and Diu was merged to form a single entity [1][2]. This administrative consolidation was executed through the Dadra and Nagar Haveli and Daman and Diu (Merger of Union Territories) Act, 2019, which was enacted by Parliament in December 2019 [2][6]. The merger officially came into effect on January 26, 2020, a date designated as 'Nirman Diwas' or 'Merger Day' [3][4]. The primary objective of this merger was to streamline administration, as both territories already shared common officials, including the Chief of Police and various Secretaries [3][5]. Following the merger, Daman was designated as the headquarters of the newly formed Union Territory [6]. This reorganization reduced the total number of Union Territories in India to eight [1].
