A Data Flow Diagram (DFD) is specifically designed to represent the flow of data within a system and to illustrate how data moves between various components. The components that make up a DFD are crucial for visualizing these interactions clearly and effectively.

Entities represent the sources or destinations of data, such as users or systems that interact with the system being modeled. Processes indicate how data is transformed or processed within the system. Data stores are places where data is held for later use, while data flows depict the movement of data between these components. Together, these elements provide a comprehensive view of how a system handles information.

The other options present terms that do not accurately fit the structure of a DFD. For example, while "Inputs" and "Outputs" are relevant to various system models, they do not specifically capture the detailed breakdown of entities and processes central to a DFD. Likewise, "Entities, Attributes, Operations, and Outputs" focuses on a different conceptual framework typically used in entity-relationship diagrams rather than in data flow representation.
