उत्तर
Both (A) and (R) are true, but (R) is not the correct explanation of (A)
Explanation:
Decomposition is the conversion of organic material into basic inorganic material. The rate of decomposition changes under the same environmental conditions because detritus composition fluctuates. The decomposition rate is slow if the waste material contains a lot of lignin and cutin.
