The correct answer is D. All of the above.
A distributed MIS structure is a type of information management system that is spread out over multiple computers. This allows for interactive sharing of the workload, as well as a multiprocessing environment. Additionally, computers supporting local DP operations can be used in a distributed MIS structure.
Option A is correct because interactive sharing of the workload is a characteristic of a distributed MIS structure. This means that users can access and update data from different locations, which can improve efficiency and productivity.
Option B is correct because a multiprocessing environment is a characteristic of a distributed MIS structure. This means that multiple computers can be used to process data simultaneously, which can improve performance.
Option C is correct because computers supporting local DP operations can be used in a distributed MIS structure. This means that data can be stored and processed locally, which can improve performance and security.
Option E is incorrect because all of the above are characteristics of a distributed MIS structure.
