Which command would be used to terminate a running process in Linux?

The command used to terminate a running process in Linux is the "kill" command. This command sends a signal to the specified process to stop its operation. By default, the kill command sends the TERM signal, which gracefully requests the process to terminate, allowing it to clean up resources and exit properly. If the process does not respond to this signal, you can use other signals, such as KILL, which forcefully terminates the process.

The other options do not function as commands for terminating processes. "Exit" is typically used to close a shell session or script but does not interact with processes. "Stop" is not a recognized command for terminating processes in Linux, and while it might suggest halting a process (which can be done with a different signal), it does not actively manage process termination like the kill command. "Terminate" is also not a valid command in this context.

Therefore, the kill command is the appropriate and widely used method for managing process termination in a Linux environment.
