Option 2 states that Haryana and Punjab have a common High Court. A High Court is the highest judicial authority within a state in India. It has jurisdiction over the state in which it is located. Option 1 states Himachal Pradesh and Uttar Pradesh have a common High Court, but this is incorrect. Each state has its own separate High Court. Option 3 states Gujarat and Maharashtra have a common High Court, which is also incorrect as they have their own separate High Courts. Option 4 states Kerala and Tamil Nadu have a common High Court, but this is incorrect as they too have their own separate High Courts. Therefore, option 2 is the correct answer as Haryana and Punjab share the same High Court, known as the Punjab and Haryana High Court.
