Which is the highest mountain in the world?

The correct answer is Everest.
Mount Everest is the highest mountain in the world above sea level. Located in the Mahalangur Himal sub-range of the Himalayas, its peak straddles the border between Nepal and China (Tibet).

Height and Discovery:

According to the most recent official surveys by Nepal and China, the height of Mount Everest is 8,848.86 meters (29,031.7 feet). It was named after Sir George Everest, a former Surveyor General of India, though its local names are Sagarmatha (in Nepal) and Chomolungma (in Tibet).

Comparison of the Options:

• Everest (8,848.86m): The absolute highest peak on Earth.


• K2 (8,611m): The second-highest mountain in the world, located on the Pakistan-China border. It is often considered more difficult and dangerous to climb than Everest.


• Nanga Parbat (8,126m): The ninth-highest mountain in the world, located in Pakistan. It is nicknamed "The Killer Mountain" due to its high fatality rate.


• Siachen: This is not a mountain peak but a glacier (the second-longest in the world's non-polar areas), located in the Karakoram range.
