A Microsoft Sentinel playbook is triggered when a Defender for AI alert fires for 'Sensitive data exposed in AI response.' The playbook must automatically post a notification to a Microsoft Teams channel with the alert details. Which Logic App action step is required for this Teams notification?

B is correct because the Microsoft Teams Logic App connector includes a 'Post a message in a chat or channel' action that directly posts formatted messages to a specified Teams channel. This is the native, purpose-built integration for posting Teams notifications from Logic App playbooks and supports rich formatting with card content. A is incorrect because while an HTTP connector with a Teams incoming webhook URL is a functional approach, the native Microsoft Teams connector is the preferred method as it provides better authentication, richer formatting options, and direct channel addressing without requiring webhook URL management. C is incorrect because sending email to a Teams channel email address creates a Teams message from email, but this is slower, adds email routing complexity, and does not format as well as native Teams messages. D is incorrect because Azure Service Bus with a separate Teams application subscriber is an unnecessarily complex event-driven architecture when direct Teams connector integration is available.
