The question requires identifying two Azure management tools that can manage web app settings from an iPhone. Azure Cloud Shell (B) provides a browser-based terminal accessible via the Azure mobile app, allowing command-line management. The Azure portal (C) is fully accessible through any supported mobile browser, including Safari on iPhone, enabling GUI-based management. Windows PowerShell (A) is incorrect as it lacks native iOS support and cannot directly manage Azure resources from an iPhone. Azure Storage Explorer (D) is incorrect because it is designed for blob and file storage management, not web app settings, and has limited mobile functionality.
