Explanations:The question asks about the oldest monastery in Sikkim, a state in northeastern India. To understand the answer, it is essential to know the historical context and the founding dates of the monasteries in Sikkim.
Dubdi Monastery, located in Gangtok, the capital city of Sikkim, is the oldest monastery in the region. It was established in the 17th century, making it the earliest among the monasteries in Sikkim. The monastery holds significant historical and cultural importance and has been a center for Buddhist learning and practice for centuries.
The other monasteries mentioned in the options are also important religious and cultural sites in Sikkim, but they were founded at different times and are not as old as Dubdi Monastery. For example, Rumtek Monastery, which is a prominent Gelugpa monastery, was established in the 20th century. Phodong Monastery, located in East Sikkim, was also founded later than Dubdi Monastery. Similarly, Pemayangtse Monastery, situated in West Sikkim, is another significant monastery but was not the first to be established in the region.
Understanding the historical context and the founding dates of these monasteries is crucial for identifying the oldest one. Dubdi Monastery's historical significance lies in its long-standing presence and its role in the cultural and religious development of Sikkim. It is a testament to the rich heritage and traditions of the region and continues to be an important site for both locals and tourists.
