The correct answer is: a) Modern-day Sikkim
The early kingdom of ‘Indrakil’ mentioned in Buddhist texts, is believed by some historians to have been located in the region of modern-day Sikkim. This is based on the fact that the name ‘Indrakil’ is similar to the name of the mountain range that runs through Sikkim, called the Himalayas. Additionally, there are a number of Buddhist temples and monasteries in Sikkim that are believed to have been built during the time of the kingdom of Indrakil.
However, there is no definitive proof that the kingdom of Indrakil actually existed. Some historians believe that it may have been a mythical kingdom, or that it may have been a real kingdom that was located in a different region.
The other options are incorrect because:
- Nepal is located to the west of Sikkim.
- Bhutan is located to the east of Sikkim.
- Tibet is located to the north of Sikkim.
