Which outcome results after increased precipitation causes amplified leaching within soil horizons?

A)Increased oxidation of iron minerals
B)Enhanced eluviation of clay particles
C)Reduced decomposition by soil microbes
D)Higher cation exchange capacity available

💡 Explanation

Enhanced eluviation of clay occurs because leaching transports clay particles through the soil profile via suspension. Therefore, the clay migrates downward, rather than iron oxidizing near the surface, microbial activity being impacted differently, or cation exchange increasing.
