Explanation

bash script.sh & is correct. Appending & to a command sends it to the background as a job, immediately returning the shell prompt so the administrator can continue troubleshooting in the same terminal session. 'source script.sh' (B) runs the script in the current shell environment in the foreground, blocking the terminal. 'sh script.sh | jobs' (C) is invalid - jobs is a shell built-in that lists background jobs and cannot be used as a pipeline destination. 'nice -10 ./script.sh' (D) adjusts the scheduling priority but still runs the script in the foreground, blocking the terminal.
