A SysOpsAdministrator is managing a large organization with multiple accounts on the Business Support plan all linked to a single payer account. The Administrator wants to be notified automatically of AWS Personal Health Dashboard events.
In the main payer account, the Administrator configures Amazon CloudWatch Events triggered by AWS Health events triggered by AWS Health triggered by AWS Health events to issue notifications using Amazon SNS, but alerts in the linked accounts failed to trigger.
Why did the alerts fail?

A. Amazon SNS cannot be triggered from the AWS Personal Health Dashboard
B. The AWS Personal Health Dashboard only reports events from one account, not linked accounts.
C. The AWS Personal Health Dashboard must be configured from the payer account only; all events will then roll up into the payer account.
D. AWS Organizations must be used to monitor linked accounts.
