Which horizon develops advanced leaching during active pedogenesis?

💡 Explanation

The E horizon exhibits depletion because it’s the zone of eluviation, an intense leaching process in pedogenesis, which removes minerals and organic matter. Therefore, a distinct light-colored E horizon forms; rather than enriching, B accumulates, C slightly alters, and O accumulates organics.
