Correct Answer:
A. Pakistan
The second highest mountain in the world is K2, also known as Mount Godwin Austen, standing at an elevation of 8,611 meters (28,251 feet). K2 is located in the Karakoram mountain range, specifically on the border between Pakistan and China. However, its most accessible and frequently used routes, including the primary base camps for climbers, are situated within Pakistan's Gilgit-Baltistan region, making Pakistan the most appropriate answer for its location.
- India is incorrect; while it has high peaks, K2 is not primarily located within its borders.
- Nepal is incorrect; it is home to Mount Everest, the world's highest peak, but not K2.
- China is partially correct as K2 is on its border with Pakistan, but Pakistan is often cited as the country where it is predominantly located or accessed.
