Which of the following are example components of BPMN?

The choice mentioning a start event, sequence flow, task, gateway (decision), and end event accurately identifies core components of Business Process Model and Notation (BPMN). BPMN is a graphical representation of business processes that enables clear communication between stakeholders.

In this notation, a start event represents the beginning of a process, setting the stage for the workflow that follows. Sequence flow indicates the order in which tasks are executed and demonstrates the flow of control from one activity to another. A task signifies a work item or operation within the process that must be completed. Gateways, which are often labeled "decision," are used to depict decision points where the flow can branch based on certain conditions. Finally, an end event signifies the completion of a process, indicating where the process flow concludes.

These elements are fundamental to BPMN's purpose of providing a standardized method to visualize and communicate the dynamics of business processes, making choice A the accurate representation of BPMN components.
