B)Increased chemical weathering rates
C)Development of karst topography
D)Regional alluvial fan expansion

Loess deposits form because fine silt and clay particles eroded by the aeolian process of deflation are transported and deposited downwind where airflow diminishes, therefore creating widespread blankets of loess, rather than localized alluvial or karst formations.
