Explanation: The question asks for the highest mountain in the world that is located in Nepal. To understand this, it is essential to know the geographical context of the Himalayas and the specific location of the highest peaks.
The Himalayas are a mountain range in Asia that includes the world's highest peaks. They stretch across five countries: India, Nepal, Bhutan, China (Tibet), and Pakistan. The Himalayas are home to many of the world's highest mountains, including the top ten highest peaks.
Among these, Mt. Everest stands out as the highest mountain in the world. It is located in the Mahalangur Himal sub-range of the Himalayas, straddling the border between Nepal and Tibet (China). The exact height of Mt. Everest has been a subject of measurement and recalibration over the years. The most recent measurement, conducted in 2020, confirmed its height at 8,848 meters (29,029 feet) above sea level.
The other options provided in the question are incorrect for the following reasons:
- Mt. McKinley (Denali) is the highest peak in North America, not the world, and is located in Alaska, USA.
- Mt. Ararat is a dormant volcanic mountain located in Turkey, not the highest mountain in the world, and not in Nepal.
- Mt. Saint Helens is an active stratovolcano located in Washington, USA, and is neither the highest mountain in the world nor located in Nepal.
Understanding the geographical context and the specific location of these mountains is crucial for correctly identifying the highest mountain in the world and its location. This knowledge is particularly important for students preparing for competitive examinations that test geographical knowledge, such as the UPSC Civil Services, SSC CGL, Bank PO, Railway Exams, and State PSC Exams.
