Explanation:

Soil that is transported and deposited by flowing water, primarily rivers, is known as Alluvial soil. These soils are typically found in river valleys, floodplains, and deltas, and are often very fertile. Option A, Colluvial soil, refers to soil material transported and deposited by gravity, usually at the base of slopes. Option C, Aeolian soil, is soil material transported and deposited by wind, such as loess. Option D, Glacial soil, is soil material transported and deposited by glaciers, forming features like moraines or till plains. Therefore, alluvial soil is the correct term for soil carried and deposited by rivers.
