To answer this question, we need to understand how to terminate a process in Linux.
Option A) kill - This option is correct because the "kill" command is used to terminate a process in Linux. The kill command sends a signal to a process, and by default, it sends the SIGTERM signal which terminates the process gracefully. If the process does not respond to the SIGTERM signal, you can send the SIGKILL signal using the "-9" option to forcefully terminate the process.
Option B) stop - This option is incorrect because there is no specific "stop" command in Linux to terminate a process. The correct command is "kill".
Option C) end - This option is incorrect because there is no specific "end" command in Linux to terminate a process. The correct command is "kill".
Option D) wait - This option is incorrect because the "wait" command is used to wait for a process to complete, not to terminate a process.
Option E) CTL-ALT-DEL - This option is incorrect because pressing "CTL-ALT-DEL" in Linux does not directly terminate a process. It opens the system's task manager, where you can manually select and terminate a process.
The correct answer is A) kill. This option is correct because the "kill" command is used to terminate a process in Linux.
