Which option commands a remote desktop for Linux?

The choice of VNC as the correct command for accessing a remote desktop in Linux is well-founded due to its design specifically for remote graphical desktop sharing. VNC stands for Virtual Network Computing, and it allows users to connect to and control a remote computer's desktop environment over a network. It transmits the graphical display from the remote machine to the client and allows for user interaction with that interface. This is particularly useful for Linux environments where users may want a graphical user interface (GUI) rather than just command-line access.

While SSH can be used for secure command-line access and can also be tunneled to run X11 applications, it does not provide a full remote desktop session out of the box. RDP, or Remote Desktop Protocol, is primarily a Windows-centric protocol, and while there are ways to use RDP on Linux, it traditionally does not natively facilitate a Linux-to-Linux remote desktop without additional configuration. X11, known as the X Window System, is a foundational technology for managing GUIs on Unix and Linux systems, but it is more focused on managing the display rather than providing a remote desktop capability as VNC does.

Therefore, VNC's focus on providing a desktop-sharing solution explicitly makes it the most suitable option
