Pakistan has four peaks higher than 8000 meters: K2, Nanga Parbat, Gasherbrum I, and Broad Peak. Therefore, the correct answer is 4, not 5.

K2 is the second highest peak in the world after Mount Everest. It stands at 8,611 meters (28,251 feet) and is located in the Karakoram range on the China-Pakistan border. Therefore, the correct answer is 'Second', which corresponds to option B.

K-2, also known as Mount Godwin-Austen, is the second highest mountain in the world and is located in the Karakoram mountain range, which spans the borders of Pakistan, India, and China.

Tirich Mir is the highest peak of the Hindu Kush mountain range, with an elevation of approximately 7,870 meters. Therefore, option C is correct.
