Explanation:

- Appropriated: This term usually refers to taking something for one's own use, often without the owner's permission, but it doesn't imply legality or authority by government.

- Confiscated: This is the correct term. It specifically refers to the legal seizure of property by authorities, often in the context of law enforcement at places like airports.

- Annexed: Typically involves adding on territory or extending control over a region, not seizing goods.

- Hijacked: Means to unlawfully seize control of a vehicle or vessel, and doesn't fit the context of seizing goods.
