Show answer & explanation
Correct answer: C
Answer: Context Diagram.
Explanation: A Level-0 Data Flow Diagram (DFD) is also called a Context Diagram. It provides a high-level view of the entire system as a single process and shows how external entities interact with the system through data flows.
Key points:
Represents the whole system as a single process (no internal decomposition).
Shows external entities (sources/sinks) and the data flows between them and the system.
Used to give stakeholders a high-level overview of system boundary and interactions.
Different from use case diagrams (functional requirements) and sequence diagrams (object interactions over time).
