Explanation
Out of the given options, only option A - Delhi has its own High Court.
The Delhi High Court was established on October 31, 1966, under the States Reorganisation Act, 1956. It has jurisdiction over Delhi and the Union Territory of Chandigarh. The High Court of Delhi is one of the five High Courts in India that has original jurisdiction in civil and criminal matters.
Option B, which includes Daman and Diu, is not correct as the Union Territory of Daman and Diu was merged with the Union Territory of Dadra and Nagar Haveli on January 26, 2020, to form a single Union Territory named Dadra and Nagar Haveli and Daman and Diu.
Option C, which mentions Puducherry, is also not correct as the Union Territory of Puducherry has a separate bench of the Madras High Court, which functions as the High Court for Puducherry.
Thus, the correct answer is A: Delhi.
