The most reliable, automated, and low-maintenance solution is to use the native Google Security Operations (SecOps) SOAR capabilities. A playbook block is a reusable, automated workflow that can be attached to other playbooks, such as the standard case closure playbook.

This block would be configured with a conditional action. This action would check a case field (e.g., case.escalation_status == "escalated"). If the condition is true, the playbook automatically proceeds down the "Yes" branch, which would use an integration action (like "Send Email" for Gmail or Outlook) to send the case details to the director. After the email action, it would proceed to the "Close Case" action. If the condition is false (the case was not escalated), the playbook would proceed down the "No" branch, which would skip the email step and immediately close the case.

This method ensures the process is "reliably sent" and "automatic," as it's built directly into the case management logic. Options C and D are incorrect because they rely on manual analyst actions, which are not reliable and violate the "automatic" requirement. Option A is a custom, external solution that adds unnecessary complexity and maintenance overhead compared to the native SOAR playbook functionality.
