Correct Answer: Lagoon

Solution : The correct answer is Lagoon.

Smaller bodies of water called lagoons are frequently isolated from the large ocean by a sandbar, reef, or barrier island. Lagoons are present in both tropical and polar regions of the planet. Lagoons are significant ecosystems that offer several advantages to both people and wildlife. They can help shield coastal communities from storms and flooding to act as vital breeding grounds for fish and other marine creatures.
