Show answer & explanation
Correct answer: B
A Level 0 Data Flow Diagram (DFD) is the highest abstraction level of a data flow diagram. It provides an overview of the entire system by treating the system as a single process and mapping out its relationship with external entities. Because it sets the boundary and "context" for the whole system, it is universally known as a Context Diagram.
