The correct answer is (B) State List – Police and Agriculture.
Police and Agriculture are subjects in the State List, on which only State governments can legislate.
The Union List includes subjects like Defence, Foreign Affairs, Banking, etc. The State List includes Police, Agriculture, Public Health, etc. The Concurrent List includes subjects like Education, Forests, Trade Unions — not Communication (which is Union). Residuary subjects (like computer software) belong to the Union, not a separate "Residuary" category. Option (B) is the only fully correct pairing, making it the right answer.
