CTRL+Z is used for?

  1. Force a process shut down.

  2. Send the current process to the background

  3. Exit the terminal

  4. Exit the current process
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

B is correct because CTRL+Z sends SIGTSTP signal, suspending the current foreground process and sending it to the background (can be resumed with 'fg' or 'bg'). A is wrong - CTRL+C (SIGINT) or 'kill' terminates processes. C is incorrect - 'exit' command closes terminals. D is partially correct but misleading - CTRL+Z suspends, doesn't exit; use 'exit' or CTRL+D to terminate.
