The correct option is Antarctica.
Explanation
The term 'Global Commons' refers to resource domains or areas that lie outside the political reach of any one nation State. According to international law, these areas belong to all of humanity and are not subject to the sovereignty of a specific country. The four recognized global commons are the High Seas, the Atmosphere, Antarctica, and Outer Space.Option Analysis
- Antarctica Antarctica: Correct. Antarctica is designated as a global common. It is governed by the Antarctic Treaty System (1959), which freezes territorial claims, prohibits military activity, and dedicates the continent to scientific research and peace.
- Sahara Sahara: Incorrect. The Sahara Desert falls within the sovereign territories of several North and West African nations, including Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Sudan, and Tunisia. It is not a global common.
- Alps Alps: Incorrect. The Alps mountain range is located entirely within the sovereign borders of eight European countries (France, Switzerland, Italy, Monaco, Liechtenstein, Austria, Germany, and Slovenia).
- Black Sea Black Sea: Incorrect. The Black Sea is an inland sea bordered by six sovereign nations (Turkey, Bulgaria, Romania, Ukraine, Russia, and Georgia). While it contains international waters, the region itself is not classified as a global common in the same legal category as the High Seas or Antarctica.
Key Takeaway:
The four major global commons recognized under international law are the High Seas, the Atmosphere, Antarctica, and Outer Space. Cyberspace is frequently debated as an emerging fifth global common.
