D had recently visited Khardung La, Nubra Valley and several Buddhist monasteries. Which one of the following States / UT had she visited ?

The traveler visited the Union Territory of Ladakh. Khardung La is recognized as one of the highest motorable passes in the world and serves as the gateway from Leh to the Nubra Valley. The Nubra Valley, located in northeastern Ladakh, is characterized by its unique landscape of cold deserts and the Shyok River [1]. This region is a significant center for Tibetan Buddhism, housing numerous gompas and monasteries. Specifically, the Diskit Monastery, founded in the 14th century, is the oldest and largest monastery in the Nubra Valley and is famous for its 106-foot Maitreya Buddha statue [1]. Other prominent monasteries in the Ladakh region include Hemis and Thiksey. While other states like Himachal Pradesh and Sikkim also have Buddhist monasteries, the specific combination of Khardung La and Nubra Valley is exclusive to Ladakh [1].
