Answer:
2. reduced record-keeping
Step-by-step explanation:
The decentralization is the chain of the processes in which the proper process of all department is followed
Just like from top-level to middle level and then lower level
And, the inverse is lower level to middle level to top level.
The authority and responsibility are delegated to each level of management so that the day to day operations could be performed in a smooth, effective and efficient manner
For the complex companies who adopt decentralization, they have all the benefits like delegation, problem identification but do not reduce record keeping as it is not an easy task for every company
Hence, option 2 is correct
