D. It is the most arid region of Mexico.

A. It is home to most of Mexico's major cities.

The correct answer is A. It is home to most of Mexico's major cities.

To determine which feature makes the Mexican Plateau significant, we can analyze the options provided:

A. It is home to most of Mexico's major cities.
B. It is the most sparsely populated area of Mexico.
C. It has the longest coastline in Mexico
D. It is the most arid region of Mexico.

To find the correct answer, we need to understand the characteristics and significance of the Mexican Plateau. The Mexican Plateau, also known as the Mexican Altiplano, is a vast elevated region located in the central part of Mexico. It is surrounded by the Sierra Madre Oriental and the Sierra Madre Occidental mountain ranges. Here, we can analyze each option:

A. It is home to most of Mexico's major cities:
The Mexican Plateau is indeed home to most of Mexico's major cities, including Mexico City, the country's capital and largest city. Other major cities like Guadalajara and Monterrey are also located within the Mexican Plateau. However, while this is a significant feature of the plateau, it may not be the most compelling reason for its overall significance.

B. It is the most sparsely populated area of Mexico:
This option is not accurate as the Mexican Plateau is not known for being the most sparsely populated area of Mexico. In fact, it is one of the most densely populated regions due to the presence of major cities and urban centers.

C. It has the longest coastline in Mexico:
This option is incorrect. The Mexican Plateau is a landlocked region and does not have a coastline. Therefore, it cannot have the longest coastline in Mexico.

D. It is the most arid region of Mexico:
This option is also not correct. The Mexican Plateau is characterized by a temperate climate with moderate rainfall and fertile soils. It is not known for being particularly arid.

Based on the explanations given, we can determine that the correct answer is A. It is home to most of Mexico's major cities. The presence of major cities within the Mexican Plateau is a significant feature that contributes to the region's importance in terms of population, economy, culture, and political influence in Mexico.
