\nThis question matches soil orders from the USDA soil taxonomy with their salient characteristics.
\n– Entisols (A): These are the youngest soils with little or no profile development and lack distinct horizons. They match “Weakly developed soils with no horizons” (2).
\n– Inceptisols (B): These soils have developed some weakly expressed horizons (incipient horizons) and are slightly more developed than Entisols but still considered young. They match “Soils having weakly or quickly developed horizons” (1).
\n– Histosols (C): These soils are composed primarily of organic materials, typically found in wet environments like swamps and bogs. They match “These soils have very high quantity of organic matter in the upper layers” (4).
\n– Oxisols (D): These are highly weathered soils found in humid tropical and subtropical regions, characterized by high concentrations of iron and aluminum oxides and deeply leached horizons. They match “These soils are very old and highly weathered” (3).
