Why each option

SSH provides encrypted command-line access over a network, while VNC provides graphical desktop access from which a terminal/shell can be launched. Both are valid tools for remote Linux shell access.

AConnect with SSHCorrect

SSH (Secure Shell) operates on TCP port 22 and opens an encrypted command shell session directly on the remote Linux host, making it the most common tool for remote CLI administration.

BConnect with RDP

RDP (Remote Desktop Protocol) is a Microsoft protocol primarily used for Windows systems and is not a standard tool for accessing a Linux command shell.

CConnect with VNCCorrect

VNC (Virtual Network Computing) transmits the graphical desktop over the network, allowing the administrator to open a terminal emulator and access a command shell remotely.

DConnect with BASH

BASH is a shell interpreter that runs locally on the server - it is not a network access protocol and cannot establish a remote connection on its own.

EConnect with FTP

FTP is a file transfer protocol used to move files between hosts, not to open an interactive command shell session.
