When the flowchart's ValidateUnconnectedNodes property is set to True, Studio checks at design time whether any activities are left unconnected and displays a validation error indicating that some activities are not connected to the others in the flowchart. This surfaces the problem immediately during design rather than deferring to runtime, so option B (silent validation with a runtime exception) is wrong; the check is native to Studio validation, not limited to the Workflow Analyzer (option C), and it produces an error, not merely an Output-panel warning (option D). The existing key of B is therefore incorrect.
