Which of the following best describes an object flow?

• A. It transports object tokens and conveys movement of matter, energy, or data between nodes.
• B. It conveys sequencing constraints among actions.
• C. It represents a time delay.
• D. It defines the boundary of a sub-activity.

Answer: (A)

Object flow in process modeling captures how objects move through a system. It shows the transfer of object tokens—representing data, materials, or other items—as they pass from one node or action to another. This is exactly what the option describes: transporting object tokens and conveying movement of matter, energy, or data between nodes. The other ideas describe different aspects of a process: sequencing constraints tell you the order in which actions must occur, a time delay represents waiting or latency, and a sub-activity boundary defines the scope of a nested or contained activity. Those are not about the movement of objects, which is the core idea of object flow.
