According to the Splunk Enterprise Security documentation, the option to create a Short ID for a notable event is located in the Event Details section of the notable event. The Event Details section shows the basic information about the notable event, such as title, description, urgency, owner, status, and others. It also provides a link to Create Short ID, which generates a 6-digit alphanumeric code that can be used to identify and share the notable event. The Short ID is appended to the URL of the Incident Review dashboard and can be used to filter the notable events by the Short ID field. See Manually create a notable event in Splunk Enterprise Security for more details. Therefore, the correct answer is B. The Event Details.
