It is a symbol that represents a physical entity that either provides or receives data to or from the system. Examples of sources and destinations include people, organizations, files, and devices.<\/p>\n<p>Option B is incorrect because an open rectangle represents a source or destination of system data, not a data flow. A data flow is a line that connects two symbols in a DFD and represents the movement of data between them.<\/p>\n<p>Option C is incorrect because an open rectangle represents a source or destination of system data, not a process. A process is a symbol that represents a transformation of data.<\/p>\n<p>Option D is incorrect because an open rectangle represents a source or destination of system data, not a data store.
