Analyze the map in order to answer the question.

A. Complex interstates in Southeast Asia are among the finest in the world.

B. Extensive bridges connect the islands of Southeast Asia with the mainland.

C. Most travel between countries happens by sea or air in Southeast Asia.

D. Public transportation is universal throughout Southeast Asia.

In order to answer the question using the map, first we need to analyze the information present on the map.

From the map, we can see that there are several lines representing roads or highways running across Southeast Asia. However, there is no specific indication of interstates. Therefore, we cannot directly conclude that complex interstates in Southeast Asia are among the finest in the world (A).

Regarding bridges, the map does not highlight specific bridges connecting islands with the mainland. Therefore, we cannot conclude that extensive bridges connect the islands of Southeast Asia with the mainland (B).

The map does depict various ports and airports across Southeast Asia. Given this information, we can infer that travel between countries in Southeast Asia mostly happens by sea or air. Therefore, statement C is likely correct, that most travel between countries in Southeast Asia happens by sea or air.

Regarding public transportation, the map does not show any specific information about the availability of public transportation throughout Southeast Asia. Therefore, we cannot conclude that public transportation is universal throughout Southeast Asia (D).

Based on the map analysis, the most accurate statement is likely C. Most travel between countries happens by sea or air in Southeast Asia.
