What does it mean to hand someone over to the legal jurisdiction of another authority?

Handing someone over to the legal jurisdiction of another authority refers to the process of extradition. This is the formal procedure through which one jurisdiction requests the surrender of a person from another jurisdiction for the purpose of facing charges or serving a sentence. Extradition typically occurs between countries or states and is governed by treaties or international agreements that outline the legal framework, rights, and obligations involved.

The other terms listed do not relate to the legal process or the context of transferring legal responsibility. For instance, "facile" typically refers to something being easily achieved or effortless, "finical" pertains to being overly particular or critical about details, and "fledge" relates to the development of birds or young creatures gaining feathers or maturity. None of these terms connect to the legal notion of jurisdiction transfer like "extradite" does. Therefore, the appropriate choice that encapsulates the meaning of handing someone over to another authority for legal reasons is indeed extradite.
