Swimmers can float in Dead sea because:
A.Winds blow at a very high speed over the surface of sea water.
B.More warm currents than cold currents originate in the sea.
C.The sea experiences more high tides than low tides.
D.The increased salt content makes the sea dense.✓ Correct
Explanation
The Dead Sea has an extremely high salt concentration (about 34%, nearly 10 times saltier than ocean water), which makes its water very dense. According to the principle of buoyancy (Archimedes' principle), a denser liquid exerts greater buoyant force, allowing objects (including swimmers) to float easily without effort. Hence option (4) is correct.
