Correct option is D

The answer is (d).
Delhi is the only union territory that has a high court of its own. The Delhi High Court was established on October 31, 1966. The other union territories, including Dadra and Nagar Haveli, Chandigarh, Andaman and Nicobar Islands, Lakshadweep, Puducherry, and Jammu and Kashmir, do not have their own high courts. The jurisdiction of the high courts of other states is extended to these union territories.
