Respuesta :
I believe it would be the last answer choice. "Earthen mounds were created for children to play on"
Mound Builders were prehistoric American Indians whose practice of burying their dead in huge mounds earned them the term.
They erected huge earthworks from the Great Lakes down to the Mississippi River Valley and into the Gulf of Mexico region beginning around three thousand years ago.
Option C is correct as the mounds were created for children to play.
Other Options are incorrect because:
- Option A is incorrect because No the bowls shaped animals were not made of stone.
- Option B is incorrect because No the portraits were not made of solid gold.
Thus Option C is correct about Mound Builder.
