Final answer:
The Maya, Aztec, and Inca all shared the critical agricultural practice of growing corn as their primary crop, which significantly influenced their societies.

Explanation:
Commonalities Among the Maya, Aztec, and Inca
The Maya, Aztec, and Inca civilizations, though distinct in many aspects, shared several important features in their agricultural practices and societal structures. One of the most significant commonalities was that they grew corn as their primary crop, which was integral to their diets and economies.
However, they did not all live in mountainous regions; for instance, the Aztecs thrived in the Valley of Mexico, while the Inca were located in the Andean mountains. Additionally, these three civilizations were not united into a single empire; they were separate entities with their own governments and territories. While they had contact with the Spanish at different historical moments, it was not a shared experience for all three, as their encounters varied in timing and impact.
Thus, while all three did grow corn as a fundamental agricultural product, the response indicating this is the most accurate choice among the options provided.
