Which soil horizon characteristic occurs because of intense chemical weathering in tropical conditions?

💡 Explanation

In tropical regions, weathering leads to intense leaching; the illuviation of iron and aluminum oxides forms lateritic horizons. Because soluble minerals are lost, this horizon appears oxide-rich rather than humus rich, mechanically fragmented, or silicate-dominated; therefore, A is correct.
