(An administrator needs to set up self-managed permissions for AWS CloudFormation StackSet operations.

Comprehensive and Detailed Explanation From Exact Extract:

To set up self-managed permissions for CloudFormation StackSet operations, two roles are required: in the administrator account, create an IAM role named AWSCloudFormationStackSetAdministrationRole to manage StackSet operations, and in each target account, create a service role named AWSCloudFormationStackSetExecutionRole that trusts the administrator account to execute the stacks. The WGU Cloud Deployment and Operations Study Guide (Section 5.4, StackSets) states, "For self-managed permissions, the administrator account requires the AWSCloudFormationStackSetAdministrationRole, while each target account needs the AWSCloudFormationStackSetExecutionRole with a trust relationship to the administrator account for stack deployment." Roles B and D are incorrectly named or misplaced.
