Explanation: Himachal Pradesh is a state in northern India, known for its diverse geography and cultural heritage. The state is divided into 12 districts, each with its own unique characteristics. The district of Lahaul & Spiti is particularly significant as it shares a boundary with Laddakh, a region in the Indian state of Jammu and Kashmir.
Lahaul & Spiti is located in the northern part of Himachal Pradesh and is known for its high mountain passes, including the famous Baralacha La and Kunzum La. The region is divided into two distinct valleys: Lahaul and Spiti. The Lahaul Valley is located to the west of the main Himalayan range, while the Spiti Valley is located to the east. Both valleys are connected by the Kunzum Pass.
The boundary between Lahaul & Spiti and Laddakh is significant for several reasons. It is a natural boundary formed by the high mountain ranges of the Himalayas. The region is known for its harsh climate and challenging terrain, which makes it a unique and important part of the state's geography.
The other options provided in the question are incorrect for the following reasons:
- Kinnaur is a district in Himachal Pradesh, but it is located to the east of the state and shares borders with Tibet and the state of Uttarakhand. It does not share a boundary with Laddakh.
- Chamba is a district in the central part of Himachal Pradesh and is surrounded by other Himachal Pradesh districts and the state of Punjab. It does not share a boundary with Laddakh.
- Kangra is a district in the southwestern part of Himachal Pradesh and is surrounded by other Himachal Pradesh districts and the state of Punjab. It does not share a boundary with Laddakh.
Understanding the geographical boundaries of Himachal Pradesh is crucial for students preparing for competitive examinations such as the UPSC Civil Services and State PSC Exams, as well as for those interested in the geography and cultural heritage of the region. The correct answer, Lahaul & Spiti, is significant due to its unique geographical location and its shared boundary with Laddakh.
