A developer has code that is stored in an Amazon S3 bucket. The code must be deployed as an AWS Lambda function across multiple accounts in the same AWS Region as the S3 bucket. An AWS CloudFormation template that runs for each account will deploy the Lambda function.
What is the MOST secure way to allow CloudFormation to access the Lambda code in the S3 bucket?

A. Grant the CloudFormation service role the S3 ListBucket and GetObject permissions. Add a bucket policy to Amazon S3 with the pnncipal of "AWS": [account numbers].

B. Grant the CloudFormation service role the S3 GetObject permission. Add a bucket policy to Amazon S3 with the principal of "*".

C. Use a service-based link to grant the Lambda function the S3 ListBucket and GetObject permissions by explicitly adding the S3 bucket’s account number in the resource.

D. Use a service-based link to grant the Lambda function the S3 GetObject permission. Add a resource of "*" to allow access to the S3 bucket.
