Which command sends the job with job id 2 to the background?

• A. kill -9 %2
• B. fg %2
• C. bg %2
• D. jobs %2

Answer: (C)

Moving a stopped or suspended job to run in the background uses the shell’s job control command with the background option. The correct way to do this for the specified job is to issue the background command with the job identifier, which tells the shell to resume that particular job in the background. Using the foreground command would bring the job to the foreground, not behind the scenes. Terminating the job with a kill signal would end it, not move it to the background. Listing jobs only shows statuses and does not change where a job runs.
