Which of the following is considered the mother civilization of Mesoamerica? A. Olmec B. Aztec C. Inca D. Maya

I think that the Olmec were considered the mother civilization of Mesoamerica.

"The concept of the Olmecs as a mother culture was first formally raised by Alfonso Caso at a 1942 conference on the "Olmec problem" in Tuxtla Gutiérrez where he argued that the Olmec were the "cultura madre" of Mesoamerica."

A. Olmec
