Which BPMN element represents who performs a set of activities within a process?

• A. Lane
• B. Data Object
• C. Data Store
• D. Event

Answer: (A)

Swimlanes in BPMN show who performs a group of activities by organizing tasks under a specific participant or role. Each lane represents an actor, and the activities inside that lane are carried out by that actor, making responsibilities and handoffs easy to follow as the process flows.

Data Object and Data Store are about information: artifacts that depict data used or produced by activities and where it’s stored. They don’t designate who does the work. Event creatures the timing or occurrence that affects the flow, not who is performing tasks. So the element that marks who handles a set of activities is the lane, often used as a swimlane to map responsibilities within a process. For example, a Sales lane might contain order-entry steps, while a Warehouse lane handles packing and shipping.
