Correct Answer:
C. Dead Sea
The correct answer is Dead Sea. The Dead Sea, located between Jordan and Israel/Palestine, is one of the saltiest bodies of water on Earth, with a salinity of about 34%, nearly ten times saltier than the average ocean. Its extremely high salt concentration allows people to float easily on its surface and prevents most aquatic life from surviving.
- Dead Sea – Correct. It has the highest salinity among major inland seas.
- Mediterranean Sea – Incorrect. It is saltier than the Atlantic Ocean but far less saline than the Dead Sea.
- Black Sea – Incorrect. It has relatively low surface salinity due to river inflow.
- Baltic Sea – Incorrect. It is one of the least saline seas in the world because of abundant freshwater input.
