Which horizon development occurs as clay minerals migrate?

💡 Explanation

Clay particle translocation by leaching causes illuviation, a process wherein mobile clay minerals are transported from upper soil horizons by percolating water and precipitate in a lower horizon, thereby forming a clay-enriched layer. Because this outcome results from subsurface migration, rather than other surficial changes, options are misdirections.
