Explanation: The Northern Mountains of India, primarily the Himalayas, are a significant geographical feature that spans several states and union territories. The Himalayas are the world's highest mountain range and play a crucial role in the geography, climate, and biodiversity of the Indian subcontinent.
Himachal Pradesh and Uttarakhand are two states that are entirely within the Himalayan range. Himachal Pradesh is located in the western part of the Himalayas and includes the Pir Panjal, Dhauladhar, and Great Himalayan ranges. Uttarakhand, on the other hand, is situated in the central part of the Himalayas and includes the Garhwal and Kumaon regions, which are part of the Great Himalayan range.
Chandigarh, while it is located in the foothills of the Himalayas, is a union territory and not a state. It is primarily a plains region and does not cover the Northern Mountains. Chandigarh is known for its urban planning and architecture, designed by the famous architect Le Corbusier, but it does not extend into the mountainous regions.
It is important to distinguish between states and union territories in the context of geographical coverage. Union territories, such as Chandigarh, are directly governed by the central government and do not have the same administrative status as states. Therefore, while Chandigarh is in close proximity to the Himalayas, it does not cover the Northern Mountains.
In summary, the correct answer is (D) Only (A) & (B), as Himachal Pradesh and Uttarakhand are the states that cover the Northern Mountains, while Chandigarh, being a union territory, does not. Understanding the geographical distribution of the Himalayas and the administrative divisions of India is crucial for correctly identifying which states and union territories cover the Northern Mountains.
