How can the user manage this?

Explanations:

Sharing the AMI with the community makes it publicly available to anyone, which is contrary to the user’s intention of sharing it only with a specific friend. An approval workflow does not restrict access to the AMI itself.

It is indeed possible to share an AMI with a selected user by using the friend’s AWS account ID. Therefore, this option is incorrect as it suggests that sharing is not possible.

The correct method to share an AMI with a specific user is to share it using the friend’s AWS account ID. This allows the specified account to have access to the AMI while keeping it private from all other users.

Sharing the AMI with a friend’s AWS login ID is not valid, as AWS uses account IDs for resource sharing. Login IDs are not used for this purpose, so this option is incorrect.
