C Correct answer
Explanation

In MPP mode, IMS processes transactions entered at terminals that are stored in message queues for later processing. This is the defining characteristic of message-based processing in IMS/DC (Data Communications). Option A is incorrect because MPP can access databases in various states depending on the specific operation. Option B is incorrect because MPP specifically uses data communication services to handle terminal input. Option D describes batch processing (BMP mode), which is the opposite of MPP.
