Explanation

Amazon S3 Lifecycle configurations are a native, built-in S3 feature specifically designed to automate object expiration. You define a rule with an expiration action set to 365 days, and S3 handles deletion automatically with zero ongoing maintenance. This is entirely serverless and requires no code. Creating an AWS Lambda function (B) requires writing, deploying, and scheduling deletion logic-unnecessary complexity when S3 handles it natively. Running a cron job on EC2 (C) requires maintaining an instance just for this task, which is high operational overhead. Using AWS Step Functions (D) requires designing a state machine and a trigger mechanism, far more complex than a simple Lifecycle rule.
