The correct answer is A - 2, B - 1, C - 4, D - 3.List I (Soil Type)List-II (Salient Characteristic)A.EntisolsWeakly developed soils with no horizons.Entisols lack any other layer except for the A horizon. They are unaltered from their parents' rock. This is a very diverse group of soils with one thing in common, little profile (horizon) development.Includes the soils of unstable environments, such as floodplains, sand dunes, or those found on steep slopes.B.InceptisolsSoils having weakly or quickly developed horizons.These soils are in the beginning stages of soil profile development.The differences between horizons are just beginning to appear.Some colour changes may be evident between the emerging horizons, and the beginnings of a B horizon may be seen with the accumulation of small amounts of clay, salts, and organic material.C.HistosolsThese soils have a very high quantity of organic matter in the upper layers. Organic matter (20-30%) and are 40 cm thick.D.OxisolsOxisols are highly weathered and old soil with the subsurface horizon being highly oxidized.Key processes include leaching and weathering.Hence, Option 1 is correct.
