Which AWS service will meet the requirement?

Explanations:

Amazon Inspector is primarily focused on security assessments for applications, including vulnerability scanning and compliance checks, but it does not specifically identify sensitive data within storage.

Amazon Macie is designed to discover, classify, and protect sensitive data stored in AWS. It uses machine learning to recognize personally identifiable information (PII) and helps organizations understand their data security posture.

AWS Identity and Access Management (IAM) is a service for managing access to AWS resources and does not analyze or identify sensitive data within storage solutions.

Amazon CloudWatch is a monitoring service for AWS resources and applications, primarily focused on logging and performance metrics, rather than identifying sensitive data.
