Material in the soils B horizon is called which of the following?

Explanation:
Soil is organized into layers called horizons. The B horizon is the layer beneath the topsoil where materials washed down from above accumulate, so it’s known as subsoil. It usually contains more clay and mineral oxides and less organic matter than the surface layer, making it denser and more mineral-rich. The topsoil, or A horizon, is richer in organic matter and nutrients from decaying plants. Humus refers to dark, decomposed organic material found mainly in the upper horizons, not the mineral-rich layer beneath. Bedrock is the solid rock beneath the soil. So the layer described is subsoil.
