The correct answer is option 1, Union. In the Indian Constitution, there are three lists - Union List, State List, and Concurrent List - which outline the powers and responsibilities of the central government, state governments, and shared responsibilities respectively. The Seventh Schedule of the Constitution contains these lists. The Union List includes matters that are under the exclusive jurisdiction of the central government. Since the "Central Bureau of Intelligence and Investigation" is a central agency, it falls under the jurisdiction of the Union government and is therefore listed in the Union list. Option 2, State, is not correct because the agency is not under the jurisdiction of any state government. Option 3, Global, is not listed in the Seventh Schedule as it is not related to the government structure of India. Option 4, Concurrent, is also not correct as the agency is not a shared responsibility between central and state governments.
