Annex meaning: which option describes the sense 'to add or attach'?

• A. To take control or possession over land without permission and often by the use of force.
• B. To detach or remove.
• C. To add or attach.
• D. To negotiate.

Answer: (C)

This sense of annex means to add or attach something to another thing, making it part of the whole. You can think of an annex added to a document or a building wing that’s joined to the main structure—an extra piece that becomes part of what’s already there. That’s why the option describing “to add or attach” fits best. The other meanings describe different uses: taking control of land without permission is a territorial or forceful sense, detaching or removing is the opposite action, and negotiating has no connection to attaching or adding.
