A company uploads large CSV files to an S3 bucket. Each file must be processed by a Lambda function to generate a report. The team wants to ensure that every file is processed exactly once and that processing starts as soon as the file is uploaded. What should the team configure?

An EventBridge rule that matches S3 object creation events and invokes the Lambda function

A scheduled Lambda function that scans the S3 bucket every minute for new files

An S3 event notification that invokes the Lambda function on s3:ObjectCreated:* events

An SNS topic that receives S3 event notifications and a Lambda subscription to process the files
