Which coastal feature consists of shallow, protected water bodies that lie between the mainland and barrier islands?

Explanation:
Lagoons are shallow, sheltered bodies of water tucked between the mainland and a barrier island. The barrier islandblocks much of the direct wave energy, creating a calm, shallow environment behind it. Water exchange with the sea can be limited or occur through tidal inlets, which shapes a brackish to sometimes salty lagoon with distinct ecological habitats like seagrass beds. Dunes are wind-sculpted sand ridges, not water bodies. Barrier flats are flat landward areas behind barriers, typically not open water. High salt marshes are vegetated wetlands along tidal zones, not protected water bodies between land and barrier islands. The description fits lagoons most directly.
