To achieve the goal, the Slack integration must be configured first so it can be selected as a notification channel. Next, an alert rule is created and scoped specifically to the "Clinical Trials" account group. Within this rule, the policies are filtered to only include those with "High" severity. Finally, the notification is set to the pre-configured Slack channel, and the frequency is set to "As it Happens" to ensure immediate notification, fulfilling all requirements in the correct operational sequence.

B: The Slack integration must be configured before it can be used in an alert rule; this option places the integration step last, which is functionally incorrect.

C: This option omits the crucial step of selecting the "Clinical Trials" account group, failing to meet the requirement of scoping alerts to that specific group.

D: The order of operations is incorrect. An alert rule must be created before its specific tabs for policy selection and notification can be configured.
