What is the notation for a call behavior action?

• A. Round-angle with this name string: <action name> : <Behavior name>
• B. Convex pentagon shaped like a signpost.
• C. Concave pentagon that looks like a rectangle with a triangular notch cut out on one side.
• D. Dashed line with an open arrowhead.

Answer: (A)

In UML activity diagrams, a Call Behavior Action is shown as a rounded rectangle—the standard action shape. Inside it, you place the action’s name, a colon, and the name of the Behavior it calls. This format, like <action name> : <Behavior name>, clearly communicates that the action triggers a predefined Behavior rather than performing a simple, standalone task. The other shapes described are not how a Call Behavior Action is represented, and the dashed line with an open arrowhead denotes a different kind of relationship or flow, not a behavior call.
