The correct answer is C. Swamps, beaches, and wetlands are all located in the Coastal Plains.

Explanation:

The Coastal Plain is a flat coastal region that runs for about 3,500 km along the coasts of the Atlantic Ocean (including the Gulf of Mexico) from New Jersey to the north, through the southeast of the United States, to reach the Yucatan peninsula in Mexico. Coastal aura does not exceed 200 meters above sea level at the highest points, and penetrates from the coast for 50–100 km towards the hinterland.

In the territory of the United States the western boundary of the coastal plain is defined by the plateau of the Piedmont and therefore the Appalachian Mountains. The eastern border is the western Atlantic coast.
