A Correct answer
Explanation

The Dead Sea has the highest salinity at approximately 34% salt content, nearly 10 times saltier than ocean water (3.5%). This extreme salarity is due to high evaporation rates in the Rift Valley and minimal outflow. The Red Sea is also very saline (4%) but less than the Dead Sea. The Black Sea has lower salinity (1.8%) due to freshwater influx, and the Mediterranean Sea is moderately saline (3.8%).
