Step-by-step explanation:
The correct answer is A) USB redirection.
USB redirection is a feature that allows USB devices connected to client computers to be redirected to the host server. This includes devices such as printers, storage devices, and audio devices. USB redirection enables users to access and use these devices on the host server, even though they are physically connected to the client computers.

This feature enhances the flexibility and convenience of using USB devices across different computers and locations.
