Correct answer
Explanation
Tibet is called the 'Roof of the World' because it has the highest average elevation of any region on Earth, with the Tibetan Plateau averaging around 4,500 meters (14,800 ft) above sea level. China, Myanmar, and Australia don't have this nickname - they're not characterized by such high plateau regions.
