Answer: Distributing pre-purchased Amazon EC2 resources across accounts.

AWS Organizations allows a company to centrally manage and govern multiple AWS accounts. One of its key features is the ability to share resources across accounts within an organization. Specifically, AWS Organizations can be used to share pre-purchased Amazon EC2 resources, such as Reserved Instances and Savings Plans, across all accounts in the organization. This helps in cost optimization and resource management, as the payer account can purchase reserved capacity that is automatically shared with all linked accounts. The other options listed are not tasks that can be directly completed using AWS Organizations. Tracking application deployment statuses globally (A) and activating DDoS protection across all accounts (C) are tasks that may involve other AWS services, but not specifically AWS Organizations. Removing unused and underutilized AWS resources across all accounts (B) is a task related to cost optimization, but it is not a direct feature of AWS Organizations. Therefore, the correct answer is D: Share pre-purchased Amazon EC2 resources across accounts.
