Which horizon ordering indicates stalled pedogenesis under permafrost?

A)O-A-Bw-C-R, active soil profile
B)O-Oe-A-E rusted iron band
C)O-Fibric-E saturated-B stagnant
D)A-Bt-C enriched clay horizon

💡 Explanation

A fibric horizon over saturated E indicates permafrost cryoturbation because freeze-thaw inhibits decomposition and mixes undifferentiated material. Therefore the soil profile remains truncated and immature rather than developing distinct Bw horizons from weathering.
