The correct choice is gleyed soil, which develops under conditions where saturation occurs for extended periods, particularly in areas with a high water table. In this scenario, the soil remains waterlogged, leading to poor drainage and an anaerobic environment. The lack of oxygen affects the soil's chemical processes, resulting in a distinct bluish-grey coloration due to iron reduction under anaerobic conditions. This is an important indicator of wetland environments and can impact plant growth and soil fertility due to the specific microbial activity in saturated soils.

The other options do not reflect the characteristics typically associated with prolonged saturation. Aerated soil refers to soil that has adequate air spaces, allowing for good oxygen flow, which is unlikely in a consistently saturated environment. Condensed soil may suggest compaction, but it does not specifically relate to water saturation or the resulting soil colors. Sandy soil, on the other hand, has good drainage and does not retain moisture well, making it unlikely to experience the saturation effects that lead to the gleying process.
