Why each option

This question focuses on configuring the WebRTC Redirector Service for Teams in Azure Virtual Desktop to control content sharing options. To restrict content sharing to only application windows, you must disable full screen sharing and enable process-specific desktop sharing.

ASet the DisableRAILScreenSharing registry key value to 1.Correct

Setting the DisableRAILScreenSharing registry key value to 1 prevents users from sharing their entire desktop or screen, restricting them from a full screen share.

BSet the UseHardwareEncoding registry key value to 1.

The UseHardwareEncoding registry key is related to video encoding performance and does not control the types of content sharing available.

CSet the ShareClientDesktop registry key value to 0.

Setting ShareClientDesktop to 0 would restrict sharing of the local client desktop, but the question specifies configuring the session host to only share from an application window.

DSet the ShareProcessDesktop registry key value to 1.Correct

Setting the ShareProcessDesktop registry key value to 1 enables the ability to share content specifically from an application window, aligning with the requirement to only support sharing from an application window.

ESet the DisableRAILAppSharing registry key value to 0.

Setting DisableRAILAppSharing to 0 would enable application sharing, which is the opposite of disabling a specific sharing type.
