D

Explanation:

The humus layer is found above the uppermost soil layer and consists mostly of organic matter that is in various stages of decomposition. The organic matter is mostly from plants but can also come from animals. In addition to the organic matter, there are also non-compacted inorganic minerals present. Underneath the humus layer, the topsoil begins and is the first official soil layer.
