Correct option is A
A – III (Vertisols): High clay content, especially smectite, which causes shrink-swell behavior.
B – IV (Gelisols): Found in cold climates with frigid/pergelic temperature regimes.
C – II (Inceptisols): Immature soils with weak horizon development.
D – I (Alfisols): Have an ochric epipedon and argillic (clay-enriched) B horizon, common in semi-arid to humid climates.
