Which one of the following National Parks has a climate that varies from tropical to subtropical, temperate and arctic?

1. The question asks to identify a National Park exhibiting a wide range of climate zones, from tropical to subtropical, temperate, and arctic. 2. Namdapha National Park, located in Arunachal Pradesh, is characterized by a significant altitudinal gradient, ranging from about 200 meters to over 4,500 meters above sea level. 3. This vast difference in altitude results in a remarkable diversity of climate zones within the park. The lower elevations feature tropical and subtropical climates, the mid-elevations have temperate climates, and the highest reaches experience alpine or arctic conditions. 4. While Khangchendzonga National Park and Nandadevi National Park also have significant altitude variations and cover temperate to alpine/arctic zones, their lower boundaries might not extend as distinctly into the tropical zone as Namdapha's. Neora Valley National Park has a smaller altitudinal range compared to the others. 5. Therefore, Namdapha National Park best fits the description of having a climate that varies from tropical to arctic. The correct option is (D).
