The answer to this is letter B. When you hear the word decomposition, the first thing that you may think about is that it is related to science. This term is being used in other industries to describe the process of breaking down the deliverable into small work packages so that they can be arranged and fixed better.
This is the same thing with what decomposers Do. Decomposers are known to be good at breaking down organic matter into smaller pieces until they become part of the soil and the soil will become more nutrient-filled to sustain the need of the plants that will grow. The business would also need sustenance to grow better.
