What steps should the DevOps engineer take to stop this?

A company is using an AWS CodeBuild project to build and package an application. The packages are copied to a shared Amazon S3 bucket before being deployed across multiple AWS accounts.

The buildspec.yml file contains the following:

The DevOps engineer has noticed that anybody with an AWS account is able to download the artifacts.

What steps should the DevOps engineer take to stop this?
A . Modify the post_build command to use –acl public-read and configure a bucket policy that grants read access to the relevant AWS accounts only.
B . Configure a default ACL for the S3 bucket that defines the set of authenticated users as the relevant AWS accounts only and grants read-only access.
C . Create an S3 bucket policy that grants read access to the relevant AWS accounts and denies read access to the principal “*”.
D . Modify the post_build command to remove –acl authenticated-read and configure a bucket policy that allows read access to the relevant AWS accounts only.
