Which command sends a job with ID 1 to the foreground?

• A. fg %1
• B. ctrl + z
• C. bg %2
• D. ctrl + c

Answer: (A)

Bringing a job to the foreground is done with the foreground control command using a specific job identifier. When you want to activate a paused or backgrounded job, you specify which one to bring forward, for example fg %1, which targets the job with ID 1 and places it back into the active, interactive session.

Other actions affect the process differently: pressing Ctrl+Z suspends the current foreground task and leaves it as a stopped job in the background; resuming a stopped job in the background uses a command like bg %2, which does not put it in the foreground; and pressing Ctrl+C sends an interrupt to terminate the current foreground process. So the exact way to move job 1 into the interactive foreground is fg %1.
