- A. Dead sea ✓
- B. Mediterranean sea
- C. Red sea
- D. South Atlantic ocean
The answer to the question is: A. Dead sea
The Dead Sea has the highest salinity among the options provided. The salinity of water is a measure of the concentration of dissolved salts. The Dead Sea, located between Israel and Jordan, is known for its extremely high salinity, which is about 34.2% – 35.5%. This high salinity is due to the fact that the Dead Sea has no outlet, causing water to evaporate and leave behind salts and minerals, resulting in a much higher salinity compared to other bodies of water.
