The waters that are located between the baseline and the territorial sea are referred to as exclusive state waters. This term encompasses those areas where a coastal state has sovereign rights and jurisdiction, predominantly concerning the natural resources and environmental regulation.

To understand this concept, it is essential to recognize that the baseline serves as the starting point from which the breadth of territorial seas and adjacent maritime zones is measured. The territorial sea typically extends 12 nautical miles from the baseline, during which the state has complete sovereignty, similar to its land territory.

While the options include several maritime zones, exclusive state waters are distinct for allowing the state to exercise rights beyond just territorial waters, particularly in resource management. This area is crucial for assessing the rights and responsibilities of coastal states under international law, especially regarding fishing and environmental protection within this defined strip of water.

The other options refer to different maritime zones: the high seas are areas beyond national jurisdiction with no state sovereignty; international waters are similar to high seas; the contiguous zone extends 24 nautical miles from the baseline, where a state can enforce laws, such as those concerning customs and immigration, but is not defined in the same resource-related terms as exclusive state waters.
