Answer: By utilizing AWS Secrets Manager to store and retrieve credentials.
The correct answer is B. AWS Secrets Manager is specifically designed to help manage, retrieve, and automatically rotate credentials securely without hardcoding them into the application code. By using AWS Secrets Manager, you can easily rotate database credentials and retrieve them whenever needed, ensuring secure credential management. Other options like IAM roles, S3 buckets, and DynamoDB tables do not provide built-in functionality for automatic credential rotation and secure retrieval specifically for this purpose.
