Graphical representations of business processes, particularly using BPMN (Business Process Model and Notation), serve as a bridge between business stakeholders and testers. These models help visualize the steps a user or system goes through, making it easier to derive test cases.

Option C is correct because acceptance testing aims to validate the system’s behavior from the user or business perspective. Therefore, focusing on key user workflows (rather than exhaustive technical or exception paths) aligns with the purpose of acceptance testing: to ensure that the system meets agreed-upon business requirements.

Option A is incorrect because decision tables are part of DMN (Decision Model and Notation), not BPMN.

Option B is too rigid — not all alternative/error paths must be modeled in early acceptance testing unless they are critical to business rules.

Option D misapplies the standards — DMN is used to model business rules, not the complete business process.

Answer: C. For acceptance testing, graphical business process models should focus on the user workflows to be tested.
