A)Vegetal organic matter reduction✓
B)Increased evapotranspiration rates
C)Quartz grain cementation decrease
D)Fluvial dissection network growth
💡 Explanation
Reduced vegetal organic matter in loess accelerates leaching because chelation, a chemical weathering mechanism, becomes less effective, therefore nutrients are more easily washed away, rather than being retained by organic compounds.
