Solution
The correct option is A Sea water is more dense than fresh water.
It is easier to swim in sea water than in river water because sea water has more density than river water. Sea water is denser because salt adds to the mass of the solution and makes the salt solution denser than it would be without salt.
We know that upthrust from water is required for swimming and the density of the fluid matters in order to gain that upthrust. The denser the fluid, more the upthrust and this is why it is easier to swim in sea water than fresh river water.
