Potential sites for future archaeological discoveries related to Sikkim’s prehistory might be located in:

The correct answer is: d) All of the above.

Potential sites for future archaeological discoveries related to Sikkim’s prehistory might be located in:

• High-altitude passes: These areas are often difficult to access, which means that they may have been less disturbed by human activity over time. This makes them a good place to find archaeological sites that have been preserved in good condition.
• Densely forested regions: Forests can provide a good environment for the preservation of archaeological sites. The trees can help to protect the sites from the elements, and the dense vegetation can make it difficult for people to access the sites, which can help to preserve them in good condition.
• River valleys: River valleys are often good places to find archaeological sites because they are areas where people have traditionally lived and farmed. This means that there is a good chance that there will be archaeological remains in these areas.

It is important to note that these are just some of the potential sites for future archaeological discoveries related to Sikkim’s prehistory. There may be other areas that have not yet been explored that could also contain important archaeological sites.
