The answer is A. systems analysis. A data flow diagram (DFD) is a graphical representation of the flow of data through a system. It shows how data is input into a system, how it is processed, and how it is output. DFDs are typically created during the systems analysis phase of systems development, which is the phase where the current system is analyzed to identify problems, opportunities for improvement, and user requirements. During this phase, the DFD is used to illustrate the current system and to identify areas where improvements can be made.
