What area does Mesoamerica encompass?

Mesoamerica is defined as a region that includes central and southern Mexico as well as parts of Central America. This area is significant for its shared cultural traits, historical developments, and indigenous civilizations, including the Aztecs and Maya, among others. The geographic boundaries of Mesoamerica are commonly set from central Mexico down through Guatemala, Belize, and parts of Honduras and El Salvador.

The correct answer reflects this broadly recognized definition, encompassing the rich cultural and historical contributions of the various peoples who inhabited this region throughout history. Other options either limit the area incorrectly or expand it beyond the notable cultural boundaries recognized by scholars in archaeology and anthropology.
