(A) Wadi Halfa Salient
(B) Nagorno-Karabakh
(C) Bajo Nuevo Bank
(D) None of these
🧠 Explanation:
- Nagorno-Karabakh is a disputed region located within the internationally recognized borders of Azerbaijan but mainly populated by ethnic Armenians.
- The long-standing conflict over this region involves two countries: Armenia and Azerbaijan.
- The conflict has led to multiple wars and ceasefires, most notably in the early 1990s and again in 2020.
- Options like Wadi Halfa Salient and Bajo Nuevo Bank refer to other geographical disputes but are unrelated to the Nagorno-Karabakh issue.
