Which statement is true regarding unmanaged packages?

Unmanaged packages are a type of package in Salesforce that allows developers to share their applications and components. The key characteristic of unmanaged packages is that they do not allow the developer to retain control over the components once they are installed in another Salesforce organization.

The correct statement regarding unmanaged packages is that the components can indeed be edited after installation. This means that once the package is installed, the recipient organization has full access to the components within it, enabling them to customize or modify these components to meet their needs. This flexibility is a significant advantage for organizations that want to adapt the shared components for their specific use cases.

The other statements do not accurately reflect the nature of unmanaged packages. The developer does not retain control over installed components, as any organization that installs the package can modify the components freely. Additionally, although unmanaged packages can contain components for transferring between environments (like sandboxes), they are not specifically designed for migration purposes like managed packages are.

In summary, the ability to edit components post-installation is the hallmark of unmanaged packages, making that the accurate statement.
