The suggested answer is C, D.
To achieve a comprehensive 360-degree view of customers across multiple Salesforce orgs, implementing a Single Package multi-org strategy would be effective. This strategy involves developing and deploying a managed package to all orgs, which reads and consolidates customer data from each org. Additionally, a Hub-and-Spoke multi-org strategy can be recommended, where customer data is consolidated in a single org that acts as the master data repository, with integration strategies enabling the other orgs to read and write to it. These options ensure data consistency and accessibility across different lines of business without necessitating a complete consolidation into a single org.
