Which of the following is a natural barrier for China?

• A. Himalayas
• B. Andes
• C. Sahara Desert
• D. Amazon River

Answer: (A)

Natural barriers are large physical features that shape how people move, defend a region, and even influence climate. The Himalayas form a massive, rugged mountain range along China’s southwestern border, rising high and running along the edge of the Tibetan Plateau. This creates a formidable obstacle to overland travel and invasion, helping protect China from large-scale incursions from the west and southwest and shaping regional weather and agriculture.

The other options are located far from China: the Andes are in South America, the Sahara Desert in Africa, and the Amazon River is in South America. None of these form a border or barrier for China. The Himalayas are the natural boundary in question.
