Which platforms allow users to download the mDL app after receiving their physical driver license?

The correct answer is based on the platforms commonly used for mobile applications compatible with most smartphones. The mDL app, which stands for mobile driver license, is specifically designed to be available on widely used mobile operating systems. Apple Store caters to iOS devices, while Google Play is the platform for downloading apps on Android devices. This broad accessibility ensures that drivers can easily download and manage their mobile licenses on their smartphones.

The other options do not provide standard platforms for mobile applications. For instance, the Microsoft Store could be linked to Windows devices, which are not the primary focus for mobile driver licenses. Similarly, the Amazon App Store, while potentially valid for some applications, is not the primary source for the mDL app. The Samsung Store and Huawei Store are specific to proprietary devices, limiting the app's reach. Lastly, Facebook and Instagram are social media platforms and do not function as app stores for downloading mobile applications.
