Which AWS service or feature should the company use?

Explanations:

AWS Cost Explorer is a tool for analyzing costs and usage but does not provide account management or billing consolidation features. It helps visualize spending but does not manage multiple accounts.

AWS Organizations allows users to create and manage multiple AWS accounts centrally. It supports consolidated billing, enabling the company to receive a single bill for all accounts, making it the best choice for central management and billing.

AWS Billing and Cost Management is a suite of tools for managing billing and costs but does not offer account management or the ability to consolidate multiple AWS accounts under one umbrella. It primarily deals with payment and usage details.

AWS Budgets enables users to set budgets for their AWS costs and usage but does not manage accounts or provide consolidated billing features. It is more focused on tracking and alerting users about budget thresholds rather than account consolidation.
