Answer:
D. Cultural regions
Explanation:
Geographers define a "cultural region" as an area or conjunction of regions that are similar in culture and environment.
Although Mexico belongs to North America, its culture, language (except Brazil, where they speak Portuguese), diversity of ethnic groups, etcetera, are more similar to those from Central and South America.
Mexico has over 70 native languages that are spoken among the tribes that still live in tight groups (Mayans, Aztecs, Lacandonans, etc), but Spanish is the main spoken language. This situation is similar to other countries in Central and South America. For instance, in Guatemala, many indigenous groups still exist, such as the K'iche, Kaqchikel, and Q'eqchi.
Therefore, these countries are incredibly rich in culture and share more characteristics between them compared to, for example, the United States and Canada.
For this reason, geographers tend to link Mexico with Central and South America due to the definition of cultural regions.
