The correct option is A Humification
The rate of catabolic action is different for different complex substances. This is known as differential decomposition. It is of two types:

Mineralisation is the process of release of minerals from the remains of organic matter.

Humification is the process by which simplified detritus gets converted into a dark formless substance known as humus. Humus is rich in cellulose, lignin, tannin, resins and it is highly resistant to microbial action. the decomposition is extremely slow.
