You are configuring a SharePoint environment to support workflows. Workflows must meet the following requirements: - Display a visual representation of the workflow. - Display the workflow history…

Business Data Connectivity Services enables external list connectivity as a data source but is not a workflow service and does not provide visual workflow representation or history on its own.

Workflow Services (SharePoint Workflow Manager integration) is the core service that provides workflow execution, history tracking, and status reporting within SharePoint. It is also required for workflows to interact with external lists exposed through Business Connectivity Services, making it central to all three stated requirements.

Access Services hosts web-based database applications within SharePoint and has no role in workflow execution, visual representation, or workflow history.

Word Automation Services performs automated document conversion tasks and is entirely unrelated to workflow management, history display, or external list access.

Visio Graphics Services renders Visio diagrams in the browser and can visualize workflow diagrams, but it is a display layer and does not independently provide workflow history or enable external list access.
