The correct one is C. The distance to the center from any boundary does not vary significantly.

The compact states is the term used to refer to countries that are characterized by having a relatively equal distance, taking as a reference point their geographic center to any of their limits with other countries or their coastline. Following the previous statement and the map, it can be stated that Burundi is a compact State because the distance from its geographic center to its borders and coastline is similar in the distance. Therefore, the correct answer is C. The distance to the center from any limit does not vary significantly.
