The descending order means arranging the peaks from the greatest height to the smallest. Mount Everest is the highest of the three, followed by Godwin-Austen (K2), and then Kanchenjunga.
Therefore the sequence is 2–3–1. The question tests comparison of mountain elevations rather than their location.
Everest lies in the Himalaya, K2 is in the Karakoram, and Kanchenjunga is in the eastern Himalaya on the India–Nepal border region. Remembering their relative heights makes it possible to solve the arrangement without calculating any values. This fact is useful in physical and human geography because it connects the location, process, and characteristic asked in the question. In examination questions, compare the wording of each option carefully and identify the specific concept rather than choosing an answer based only on a familiar term.
