A Correct answer
Explanation

The correct command is 'fg' (foreground), which by default operates on job specifications, not PIDs. To move a background job to foreground, use 'fg' or 'fg %jobnum'. Using 'fg pid' is technically incorrect syntax - fg expects a job ID (like %1), not a process ID. However, option A is intended as the correct answer among the choices.
