Final answer:
Extradition fits within the form of cooperative federalism, where both national and state governments coordinate their actions to enforce laws across state lines.
Step-by-step explanation:
Extradition would most appropriately fit within the concept of cooperative federalism. Under this form of federalism, both the national and state governments coordinate their actions to solve national problems and manage policy programs, leading to a blending of layers, similar to a marble cake.
Extradition, the process by which one jurisdiction surrenders a suspect to another jurisdiction where the suspect has been accused of or convicted of a crime, requires cooperation between the states and federal government, as guided by the Full Faith and Credit Clause of the Constitution, demonstrating how they work together to enforce laws and maintain justice across state lines.
