Early Mesoamerican civilizations primarily relied on squash, corn, and beans due to their suitability to the region's climate and their role in sustainable agricultural practices. These three crops are known as the "Three Sisters" and form the basis of Mesoamerican agriculture, as they complement each other nutritionally and help optimize growing conditions. For example, corn provides a structure for beans to climb, beans enrich the soil with nitrogen, and squash's broad leaves help prevent weeds and retain soil moisture.

This combination was vital for the dietary needs of these civilizations, contributing essential carbohydrates, proteins, and nutrients. The significance of these staples in Mesoamerican culture and cuisine is profound, as they not only sustained the population but also played a role in rituals and economic exchanges. Other options, while they mention food sources, do not accurately reflect the core agricultural practices of early Mesoamerican societies.
