A company's SysOps administrator has created an Amazon EC2 instance with custom software that will be used as a template for all new EC2 instances across multiple flaws accounts. The Amazon Elastic Block Store (Amazon EBS) volumes that are attached to the EC2 instance are encrypted with flaws managed keys.
The SysOps administrator creates an Amazon Machine Image (AMI) of the custom EC2 instance and plans to share the AMI with the company's other flaws accounts. The company requires that all AMIs are encrypted with flaws Key Management Service (flaws KMS) keys and that only authorized flaws accounts can access the shared AMIs.
Which solution will securely share the AMI with the other flaws accounts?

A. In the account where the AMI was created, create a customer managed KMS key. Modify the key policy to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the flaws accounts that the AMI will be shared with. Modify the AMI permissions to specify the flaws account numbers that the AMI will be shared with.

B. In the account where the AMI was created, create a customer managed KMS key. Modify the key policy to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the flaws accounts that the AMI will be shared with. Create a copy of the AMI, and specify the KMS key. Modify the permissions on the copied AMI to specify the flaws account numbers that the AMI will be shared with.

C. In the account where the AMI was created, create a customer managed KMS key. Modify the key policy to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the flaws accounts that the AMI will be shared with. Create a copy of the AMI, and specify the KMS key Modify the permissions on the copied AMI to make it public.

D. In the account where the AMI was created, modify the key policy of the flaws managed key to provide kms:DescribeKey, kms:ReEncrypt*, kms:CreateGrant, and kms:Decrypt permissions to the flaws accounts that the AMI will be shared with. Modify the AMI permissions to specify the flaws account numbers that the AMI will be shared with.
