Explanation

'atq' lists all pending at jobs along with their job numbers and scheduled times. This is the first necessary step: identify the job number of the reboot task. Once the job number is known, 'atrm <job_number>' would be used to remove it. None of the other options (at -q) are valid at command flags for listing jobs. Although 'atq' alone does not remove the job, it is the correct starting point in the removal process and is the only valid command among the choices provided. Options A and C are both 'atq'; the answer is effectively 'atq'.
