Option 1 -> Agriculture is Entry 14 in the State List, so states have the power to legislate on it.
Option 2 -> Cyber Laws didn't exist when the Constitution was drafted (1949-50), so it's not mentioned in any of the three lists and falls under Residuary Powers.
Option 3 -> Forest is Entry 17A in the Concurrent List (added by 42nd Amendment), allowing both Union and States to legislate.
Option 4 -> Prison is Entry 4 in the State List, giving states the authority to make laws on it.
Hence, Option 2: Cyber Laws -> Since subjects like internet, computers, and cyber laws emerged after the Constitution was framed, they were not included in the Union, State, or Concurrent Lists. Under Article 248, such matters fall under Residuary Powers, enabling the Union Government to enact legislation like the Information Technology Act, 2000 -> correct
