A person would not drown in the dead sea or a salty lake even if the person does not know how to swim. This is due to :
Answer: C
A person does not drown in the Dead Sea because of the high density of sea water.
The Dead Sea contains so much dissolved salt, roughly ten times as much as ordinary seawater, that its density is far greater than that of fresh water and greater than that of the human body. By Archimedes' principle, a floating body displaces its own weight of liquid; in such dense water a person needs to sink only a little way to displace enough, so the person floats easily.
Low density would make sinking easier, not harder. The total volume of water does not affect whether something floats, and 'neither high nor low density' gives no reason at all.
