Which of the below mentioned services will help the admin setup notifications?

Explanations:

AWS SES (Simple Email Service) is used for sending and receiving emails, not for setting up event notifications for RDS.

AWS CloudTrail records API calls for auditing purposes, but it does not specifically handle event notifications for RDS.

AWS CloudWatch monitors AWS resources and applications, but does not directly handle event notifications for RDS by itself.

AWS SNS (Simple Notification Service) is designed for setting up notifications and alerts. It integrates with other AWS services, including RDS, to send notifications based on events.
