Solution

The correct option is B Saturated salt solution,it is denser than water
b'
Buoyant force, F = $V \times ρ \times g$
(where, $ρ$ = Density of water, V = Volume of water displaced by the body)
Buoyant force depends upon volume and density, since, saturated salt solution have higher density than the water. So, in saturated solution, cube will experience a greater buoyant force.
