What is the term for the surrender by one state or country to another of an individual accused of a crime?

The correct term for the surrender by one state or country to another of an individual accused of a crime is extradition. Extradition is a legal process whereby one jurisdiction delivers a person to another jurisdiction where that person is wanted for prosecution or to serve a sentence. This process typically requires a formal agreement between the involved parties, ensuring that the rights of the accused are upheld during this transition.

Incarceration refers to the confinement of an individual in a jail or prison, which is a different concept focused on serving a sentence after conviction rather than the process of surrendering an individual between jurisdictions. Detainment, while it involves holding an individual for questioning or investigation, does not imply that the individual is being handed over to another legal authority. Apprehension involves the act of arresting a person but does not convey the transfer of that person from one jurisdiction to another, as extradition does. Thus, the precise definition of extradition makes it the correct choice in this context.
