Correct Answer:
A. k2
This question asks to identify the highest mountain peak within Pakistan's territory. Pakistan is home to some of the world's most formidable mountains, particularly in the Karakoram and Himalayan ranges. K2, also known as Mount Godwin Austen, is unequivocally the highest peak in Pakistan and the second-highest mountain in the entire world, standing at an elevation of 8,611 meters (28,251 feet). It is a part of the Karakoram mountain range.
- Nanga Parbat is the ninth-highest mountain globally and the second-highest in Pakistan, making it incorrect for the "highest" designation.
- Rakaposhi is a stunning peak in the Karakoram, but its elevation is considerably lower than K2, thus not the highest.
- Gasherbrum I, also known as Hidden Peak, is the 11th highest mountain in the world and the third-highest in Pakistan, again not the highest overall.
K2's immense height makes it Pakistan's undisputed highest point.
