The method to terminate a running process in Linux is by using the kill command followed by the Process ID (PID). The kill command sends a signal to the specified process, instructing it to terminate. By default, it sends the SIGTERM signal, which requests the process to shut down gracefully, allowing it to clean up resources before exiting.

This is a fundamental command in Linux for process management, enabling users and administrators to control running applications and scripts. Understanding how to use the kill command effectively is essential for system administration and troubleshooting.

Although the other options sound plausible, they do not correspond to valid Linux commands. For instance, 'stop' does not exist as a standard command in this context, while 'terminate' and 'end' are also not recognized commands for process termination in Linux. Therefore, the recognized and effective method for terminating a process remains the use of the kill command with the appropriate PID.
