Answer: AWS Organizations

The correct answer is B, AWS Organizations. AWS Organizations is designed to consolidate multiple AWS accounts into a single organization, providing centralized management and billing. This service allows businesses to better control their budget, security, and compliance needs across all accounts within the organization. The other options, such as AWS Systems Manager, AWS License Manager, and Cost Explorer, serve different purposes and do not provide the consolidated billing feature required in this scenario.
