Detailed Solution

According to Archimedes’ principle, when a body is immersed fully or partially in a liquid, it experiences an upward force that is equal to the weight of the liquid displaced by it.
The upward force exerted by the liquid on the body is known as upthrust or buoyant force.
Since buoyant force is equal to the weight of the displaced liquid, it is proportional to the density of the liquid.
Since a saturated salt solution is denser than water, the cube will experience a greater buoyant force in a saturated salt solution.

Therefore, 'Saturated salt solution' is the correct response.
