E.    Use the x:id property for all of the controls that require localization.
F.    In a subfolder of the app, create three .resw files.

Answer: ADF
Explanation:
* From scenario: The app interface must be available in English, Spanish, and French.
A (not C): You can load string resources from objects such as resource files, libraries, controls, and Windows Store app packages and manifests.
* Example: var res = Windows.ApplicationModel.ResourceLoader('Errors'); res.GetString('AlreadyRegistered');
D (not E): x:Uid directive
Provides a unique identifier for markup elements. For Windows Runtime XAML, this unique identifier is used by XAML localization processes and tools, such as using resources from a .resw resource file.
F (not B): Windows Store apps that use XAML
For Windows Store apps that use XAML, you localize these fields in resources.resw files by using the Resource Editor.
To create the United States English version of the manifest fields, you would add an en-usresources.resw file.
