A Salesforce contractor has built an application for Universal Containers (UC) .The contractor will need to deploy multiple times from the…

An unmanaged package is the appropriate mechanism for this scenario. It allows the contractor to bundle the application components and deploy them to Universal Containers' (UC) unrelated Salesforce environments. Once installed, all components of an unmanaged package, including Apex code, are fully visible and editable in the subscriber's (UC's) org. This directly meets the requirement that UC has full control of the application's code and its intellectual property. It is designed for one-time distribution or for code that the recipient will own and maintain.

A. The Eclipse IDE is a development tool used to write and deploy metadata, not a distribution package mechanism for transferring ownership of an application between parties.
C. Change Sets can only be used to deploy between orgs that are connected through a deployment connection, such as a sandbox and its production org, not between two unrelated orgs.
D. A Managed Package protects the intellectual property by obscuring the source code, which contradicts the requirement for UC to have full control and ownership of the code.

2. Salesforce Developer Documentation, Packages, "Comparing Managed and Unmanaged Packages": "Unmanaged packages are unmanaged. The developer who created and uploaded the unmanaged package has no control over the installed components, and can't upgrade them."
