Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The nohup (no hang up) command prevents a background process from terminating when the user logs off or disconnects. It runs the command that ignores the SIGHUP signal. Option B is correct. The ampersand (&) merely backgrounds a process but doesn't protect it from hangups. Options C and D are not relevant commands for this purpose.
