An organization wants to share a central AWS Transit Gateway and Amazon Route 53 Resolver rules across 50 AWS accounts. What is the MOST efficient way to manage this sharing?

Create IAM cross-account roles in the central account for each of the 50 member accounts.

Use AWS Resource Access Manager (RAM) to share the resources with the entire AWS Organization.

Configure VPC peering from the central account to all 50 member accounts.

Use AWS Service Catalog to provision the resources in each account.
