Selected Answer: C

In a Data Flow Diagram (DFD), a Data Process (often simply referred to as a "process") represents an activity or function that transforms input data into output data. This transformation can involve combining, modifying, or organizing data in some way. Processes are usually depicted as circles or rounded rectangles and are the core components in a DFD, showing how data is acted upon within the system.
