Geography

The height of the Himalaya range generally increases as it moves from west to east, with the highest peaks located in the eastern part of the range, such as Mount Everest. Therefore, the correct direction is from West to East.

The Karakoram mountain range has an average height of about 20,000 feet, which converts to approximately 6,100 meters. This is supported by authoritative sources such as Encyclopaedia Britannica. While the range includes some of the world's highest peaks like K2 (8,611 meters), the average elevation of the entire range is closer to 6,100 meters rather than 7,500 meters. Therefore, the closest option to the average height is 7,000 meters (option A), which is more reasonable than 7,500 meters.

The Siachen Glacier is approximately 76 kilometers long, making option B the correct answer. This length is well-documented in geographical and environmental studies related to the region.

Batura Glacier is the second longest glacier outside the polar regions, after the Siachen Glacier, making it the second highest in terms of length. Siachen Glacier is the longest glacier outside the polar regions, so it is the highest, not the second highest.

Nanga Parbat is the ninth highest mountain in the world and is part of the Himalayas mountain range located in Pakistan. It is not part of the Hindu Kush, Karakoram, or Pamir ranges.

K-2 is the second highest mountain in the world and is also known as Mount Godwin-Austen. It is located in the Karakoram range on the border between Pakistan and China. The name 'Broad Peak' refers to a different mountain near K-2, not K-2 itself. Therefore, the correct alternative name for K-2 is 'Godwin Austin' (option A).

Pakistan has seven peaks above 8,000 meters, including K2, Nanga Parbat, and five others. This makes option A correct, as the country is home to seven such high peaks in the Karakoram and Himalaya ranges.

Broad Peak is a mountain in the Karakoram range located on the border of Pakistan and China. Its widely accepted official height is 8,051 meters (26,414 feet), making option C (8075 meters) the closest to the verified height. The originally given option A (8126 meters) is incorrect for Broad Peak; 8126 meters corresponds to the height of Nanga Parbat, another peak in Pakistan. Therefore, the correct height for Broad Peak is approximately 8,051 meters, which is closest to option C (8075 meters) among the given choices.

Gasherbrum I is commonly known as Hidden Peak due to its remote location and challenging climbing conditions. This is a well-established alternate name for the mountain.

K-2 is the highest peak in the Himalayas range located in Pakistan, standing at 8,611 meters. Nanga Parbat is also a high peak but lower than K-2. Therefore, option B is correct.
