- Nepal.
Explanation:
Nepal.Reaching 29,029 feet (8,848 meters) above sea level, Mount Everest is the highest mountain on Earth. Located in the Mahalangur section of the Himalayas, the mountains summit straddles the border separating China.
The mountains height was first determined in 1856. The Great Trigonometric Survey of British India pegged the mountain, known to them as Peak XV, at 29,002 feet (8,840 meters). But those surveyors were at a disadvantage because Nepal would not grant them entry due to concerns that the country would be invaded or annexed. The current accepted elevation was determined by an Indian survey in 1955 and backed up by a 1975 Chinese measurement.
