Which AWS service will help identify the cause and determine which user deleted the resources?

Explanations:

AWS CloudTrail records account activity, including actions taken by users and services, enabling visibility into resource creation, modification, and deletion.

Amazon Inspector is a security assessment service focused on identifying security vulnerabilities, not tracking user actions or resource changes.

Amazon GuardDuty is a threat detection service that monitors for malicious activity but does not provide details on resource deletions.

AWS Trusted Advisor offers recommendations for cost optimization, security, and performance but does not track user actions on resources.
