The correct choice, which identifies the soil type formed through wind deposition, is Eolian. Eolian soils are characterized by particles that have been transported and deposited by wind activity. This process typically occurs in arid or semi-arid regions, where loose sand and silt can be easily picked up by wind currents. As the wind moves these materials, they eventually settle in areas where the wind's velocity decreases, leading to the accumulation of these windblown particles.

The other options represent different types of soil formation processes. Colluvial soils are formed from materials that are moved downhill due to gravity, typically from slope erosion. Lacustrine soils develop in sedimentary environments around lakes, where materials settle in still waters. Outwash soils are created from sediments laid down by glacial meltwater, which carry a mix of materials as they flow away from a glacier. These distinctions highlight the unique processes underlying the formation of each soil type, emphasizing the specific nature of Eolian soils as those shaped by wind action.
