Selected Answer: A
A customer-managed prefix list in AWS allows you to create a list of IPv4 addresses and prefixes that can be shared with multiple resources across accounts and regions. This makes it suitable for managing a list of on-premises IPv4 hosts that need access to AWS resources. This solution provides a centralized and version-controlled way to manage the list of IPv4 addresses, ensuring consistency and ease of updates across multiple accounts in the AWS organization.
