Which statement describes events in BPMN?

• A. An event is something that happens during a process and is represented with a circle
• B. An event is a type of data object
• C. An event is always the starting point
• D. An event is represented by a square

Answer: (A)

In BPMN, an event is something that happens during a process and is shown as a circle on the diagram. That circular symbol makes events easy to spot and distinguishes them from other elements like activities (rounded rectangles), gateways (diamonds), and data objects (cylinders). Events aren’t limited to the start of a process; they can occur at any point to indicate a trigger, a result, or a boundary condition, such as a timer firing or a message arriving. This is why the statement describing an event as something that happens during a process and is represented with a circle is the best choice. The other descriptions don’t fit: an event isn’t a data object, it isn’t always the starting point, and it isn’t represented by a square.
