Quizplus · Accepted Answer

An internal entity in a physical DFD represents a component or module within the system that transforms data. Therefore, D is the best choice. Data flows represent the movement of data between entities, data stores, and processes, but they do not transform data. Data stores represent where data is stored and retrieved but do not transform it. External entities represent outside sources or destinations of data.
