Which of the following statement is correct?
(1) Humification and mineralisation occur during decomposition in the soil
(2) Sunlight and soil porosity are the most important climatic factors that regulate decomposition
(3) Warm and moist environment favour decomposition
(4) Decomposition is largely an oxygen-requiring process
Choose the correct answer from the options given below:

Correct option is C

Temperature and soil moisture are the most important climatic factors that regulate decomposition through their effects on the activities of soil microbes. Warm and moist environment favour decomposition whereas low temperature and anaerobiosis inhibit decomposition resulting in build up of organic materials.
