A) Nothing, just totally naked
B) What you’re wearing and anything you carry with you (even if you’re not carrying it right now) like a bag
C) What you’re wearing, what you carry with you, and the contents of your home (it will be teleported within a few hundred metres on the surface in an accessible location, but obviously won’t be connected to any services like electricity or water)
If I have the contents of my home, then I probably have enough scientific knowledge in the form of books to start my own scientific revolution provided I can get enough people to listen to me.

Do you speak whatever language they spoke in Peru in the year 3000?
Can you learn it before you become the main offering in a ritual sacrifice?
Why would they start sacrificing people out of blue?

Looks like all cultures that lived in territories of modern Peru only sacrificed children, so question stands. 🙃
Maybe time travel makes the traveller look like a children once it arrives.
