The correct answer is A) constructed giant stone monuments.
The Olmec people constructed giant stone monuments.
The Olmec people were a Mesoamerican civilization that inhabited the territories of what today are the states of Veracruz and Tabasco, along the coast of the Gulf of México. Historians consider that they stay there from 1200 BCE to 400 BCE. They were known for their massive stone sculptures, their sacred temples, and the famous ball game. The massive stone heads that they built, can be visited in the great Nature Park called "La Venta," in Tabasco city and the Xalapa Museum, in Xalapa, the capital city of the state of Veracruz.
