B. A-III, B-IV, C-II, D-I

Step-by-step solution

Decomposition is the process of breaking down complex organic matter into inorganic substances like carbon dioxide, water, and nutrients. Detritus constitutes the dead remains of plants and animals, including faecal matter, which serves as the raw material for decomposition. Mineralisation is the process by which microbes further degrade humus to release inorganic nutrients into the soil. Humification leads to the accumulation of a dark-coloured, amorphous, colloidal substance called humus, which is highly resistan
