The correct option is Banking.
Explanation
The Seventh Schedule of the Indian Constitution (Article 246) demarcates the legislative powers between the Union and the States into three lists: the Union List (List I), the State List (List II), and the Concurrent List (List III). The Union Parliament has exclusive power to make laws with respect to any of the matters enumerated in the Union List.Option Analysis
- Banking is Correct: Banking is listed under Entry 45 of the Union List. Subjects like banking, currency, and coinage require a uniform financial system across the country and are therefore placed under the exclusive jurisdiction of the Union.
- Agriculture is Incorrect: Agriculture, including agricultural education and research, falls under Entry 14 of the State List. It is considered a subject of local importance best managed by State governments.
- Trade Unions is Incorrect: Trade Unions; industrial and labour disputes are listed under Entry 22 of the Concurrent List. Both the Parliament and State Legislatures can frame laws regarding this subject.
- Police is Incorrect: Police (including railway and village police) is listed under Entry 2 of the State List, making it a primary responsibility of the State governments to maintain public order.
Key Takeaway: Subjects of national importance requiring uniformity (e.g., Banking, Defence, Foreign Affairs) are in the Union List, while subjects of local administration (e.g., Police, Agriculture, Public Health) are in the State List.
