How can the developer enforce that all requests to retrieve the data provide encryption in transit?

A : Define a resource-based policy on the S3 bucket to deny access when a request meets the condition “aws:SecureTransport”: “false”.

B : Define a resource-based policy on the S3 bucket to allow access when a request meets the condition “aws:SecureTransport”: “false”.

C : Define a role-based policy on the other accounts' roles to deny access when a request meets the condition of “aws:SecureTransport”: “false”.

D : Define a resource-based policy on the KMS key to deny access when a request meets the condition of “aws:SecureTransport”: “false”.
