A company wants to improve cost awareness for its Amazon EMR platform. The company has allocated budgets for each team’s Amazon EMR usage. When a budgetary threshold is reached, a notification should be sent by email to the budget office’s distribution list. Teams should be able to view their EMR cluster expenses to date. A solutions architect needs to create a solution that ensures the policy is proactively and centrally enforced in a multi-account environment.
Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)

A. Update the AWS CloudFormation template to include the AWS::Budgets::Budget::resource with the NotificationsWithSubscribers property.
B. Implement Amazon CloudWatch dashboards for Amazon EMR usage.
C. Create an EMR bootstrap action that runs at startup that calls the Cost Explorer API to set the budget on the cluster with the GetCostForecast and NotificationsWithSubscribers actions.
D. Create an AWS Service Catalog portfolio for each team. Add each team’s Amazon EMR cluster as an AWS CloudFormation template to their Service Catalog portfolio as a Product.
E. Create an Amazon CloudWatch metric for billing. Create a custom alert when costs exceed the budgetary threshold.
