Which term describes areas that share a common border?

Explanation:
Sharing a boundary means the areas are contiguous. Contiguity specifically captures the idea of touching along a border to form a single, connected region. That border-to-border contact is what the term emphasizes, making it the best fit for “areas that share a common border.” If areas don’t touch at all, they’re noncontiguous or disjoint, and if they’re only near each other without definitely sharing a boundary, the term wouldn’t be as precise. An example is neighboring states that meet along a shared line of border—those are contiguous.
