Which of the following represent levels in business process modelling?

In business process modeling, the levels typically describe different aspects of a process. The correct choice emphasizes the distinction between the entities involved in the business processes and the actions taken within those processes.

The combination of "Actor" and "Response" refers to the individuals or systems that perform tasks and the reactions or outputs that result from those tasks. Similarly, "Event" and "Task" relate to specific occurrences that trigger activities and the actions that are executed in response. Recognizing these levels is crucial as it helps in delineating the roles, actions, and outcomes within a business process.

This choice effectively showcases how actors interact with processes and the significance of both events and tasks in the operation of the business, thus providing a clear understanding of the dynamics at play in business process modeling. Understanding these levels is essential for accurately mapping out processes and ensuring that all relevant components are captured in a model.
