Question
A developer creates an AWS Lambda function that runs when an object is put into an Amazon S3 bucket. The function reformats the object and places the object back into the S3 bucket.

What should the SysOps administrator do to stop the loop without errors?
Options
- ADelete all the objects from the S3 bucket.

- CUpdate the S3 bucket policy to deny access for the function.
- DPublish a new version of the function.
