Consolidated billing process
AWS Organizations provides consolidated billing so that you can track the combined costs of all the
member accounts in your organization. The following steps provide an overview of the process for
creating an organization and viewing your consolidated bill.
1. Open the AWS Organizations console or the AWS Billing and Cost Management console. If you open
the AWS Billing and Cost Management console, choose Consolidated Billing, and then choose Get
started. You are redirected to the AWS Organizations console.
2. Choose Create organization on the AWS Organizations console.
3. Create an organization from the account that you want to be the management account of your new
organization. For details, see Creating an Organization. The management account is responsible for
paying the charges of all the member accounts.
4. (Optional) Create accounts that are automatically member to the organization. For details, see
Creating an AWS account in Your Organization.
5. (Optional) Invite existing accounts to join your organization. For details, see Inviting an AWS account
to Join Your Organization.
6. Each month AWS charges your management account for all the member accounts in a consolidated
bill

C is the right answer
“When you invite an account, AWS Organizations sends an invitation to the account owner, who decides whether to accept or decline the invitation. You can use the AWS Organizations console to initiate and manage invitations that you send to other accounts. You can send an invitation to another account only from the management account of your organization.
If you are the administrator of an AWS account, you also can accept or decline an invitation from an organization. If you accept, your account becomes a member of that organization. Your account can join only one organization, so if you receive multiple invitations to join, you can accept only one. “
