Which AWS service enables the company to reduce costs by controlling access to AWS services for all AWS accounts?

Explanations:

AWS Cost Explorer allows users to visualize and analyze their spending, but it does not provide the ability to control access to AWS services or restrict unauthorized usage.

AWS Config provides a way to assess, audit, and evaluate configurations of AWS resources, but it does not directly control access to services or manage costs.

AWS Organizations enables central governance of multiple AWS accounts, including the ability to set policies that control access to specific AWS services, thereby reducing unauthorized usage and controlling costs.

AWS Budgets allows users to set cost and usage budgets, but it doesn’t directly control access to AWS services. It only helps in tracking spending and receiving alerts when thresholds are breached.
