Which statement correctly defines an initial node?

• A. Marks the starting point of an activity
• B. Ends the activity
• C. Represents a decision point
• D. Denotes a parallel fork

Answer: (A)

An initial node marks where the workflow begins. In activity diagrams, control flows originate from this starting point and move to the first action or activity, so identifying it as the starting point of an activity is exactly what it does. The other elements describe other parts of the diagram: an end node signals completion of the activity; a decision point directs flow based on conditions; a parallel fork splits the flow into concurrent paths. So you start the process at the initial node and then proceed to the first step.
