A company wants to tag and track AWS usage costs by business category. Which AWS feature or service should they use to accomplish this?

Cost allocation tags are key-value pairs that you can apply to AWS resources to organize your costs. When activated, AWS includes these tags in your cost and usage reports, allowing you to categorize and track costs by business category, project, or owner. This directly addresses the need to tag and track usage costs by business category. AWS Organizations helps manage multiple AWS accounts but doesn't directly tag costs within an account. AWS Security Hub is for security posture management, not cost tracking. AWS Cost and Usage Report provides detailed cost data but relies on tags for categorization; it doesn't create the tags itself.
