The Lepcha people’s oral traditions and mythology might hold clues about:

Prehistoric events and beliefs
Trade routes across the Himalayas
The arrival of Buddhism in Sikkim
Conflicts with neighboring kingdoms

The correct answer is: a) Prehistoric events and beliefs.

The Lepcha people are an indigenous ethnic group of the Himalayas. They have a rich oral tradition that includes myths, legends, and folktales. These stories can provide valuable insights into the Lepcha people’s history, culture, and beliefs.

For example, one Lepcha myth tells the story of how the world was created. According to the myth, the world was originally a vast ocean. One day, a giant bird landed on the water and laid an egg. The egg hatched, and the world as we know it was born.

This myth provides valuable insights into the Lepcha people’s worldview. It shows that they believe that the world was created by a divine being, and that the natural world is sacred.

Other Lepcha myths and legends tell stories about the Lepcha people’s ancestors, their interactions with other cultures, and their experiences with colonialism. These stories can help us to understand the Lepcha people’s history and culture.

The Lepcha people’s oral tradition is a valuable resource for understanding their history, culture, and beliefs. It is important to preserve this tradition so that future generations can learn about the Lepcha people’s rich heritage.

The other options are also possible, but they are less likely to be the focus of Lepcha oral traditions. Trade routes across the Himalayas, the arrival of Buddhism in Sikkim, and conflicts with neighboring kingdoms are all important historical events, but they are not as central to the Lepcha people’s identity as their prehistoric events and beliefs.
