Each path of execution through a use case from beginning to end is a distinct _______.

Each path of execution through a use case from beginning to end is a distinct _______.

• A. Scenario
• B. Trigger
• C. Subject
• D. Extensions

Answer: (A)

In use-case thinking, a complete sequence of events from the moment the use case starts to when it ends represents one specific way the goal can be achieved. That end-to-end path is called a scenario. It captures the exact flow of steps, including decisions and actions, for that particular instance. A trigger is only what starts the use case, not the whole sequence. The subject is the system or entity being modeled, not the flow of events. Extensions are points where the flow can branch into variations, but they describe alternate paths rather than the single end-to-end path. So the distinct end-to-end path is a scenario.
