When the developer deploys the AWS SAM template in the eu-west-1 Region, the creation of the stack fails.

Which of the following could be the reason for this issue?

Options:

A.

CloudFront distributions can be created only in the us-east-1 Region.

B.

Lambda@Edge functions can be created only in the us-east-1 Region.

C.

A single AWS SAM template cannot contain multiple Lambda functions.

D.

The CloudFront distribution and the S3 bucket cannot be created in the same Region.
