An organization is running multiple applications for their customers. Each application is deployed by running a base AWS CloudFormation template that configures a new VPC. All applications are run in the same AWS account and AWS Region. A SysOps administrator has noticed that when trying to deploy the same AWS CloudFormation stack, it fails to deploy.
What is likely to be the problem?

A. The Amazon Machine image used is not available in that region.
B. The AWS CloudFormation template needs to be updated to the latest version.
C. The VPC configuration parameters have changed and must be updated in the template.
D. The account has reached the default limit for VPCs allowed.
