Soil bacteria like Bacillus, Actinomycetes slowly and gradually breakdown the dead plant and animal bodies or detritus into smaller fragments.

Given below are two statements:

Statement $\mathrm{I}$: Decomposition is a process in which the detritus is degraded into simpler substances by microbes.

Statement $\mathrm{II}$: Decomposition is faster if the detritus is rich in lignin and chitin.

In light of the above statements, choose the correct answer from the options given below:

Select the correct option for the process of decomposition.

a = Fragmentation

b = Catabolism

c = Leaching
