A Linux administrator needs to schedule a backup job to run every Friday at 2:15 a.m. Which of the following lines should the administrator add to the crontab file?

The crontab format follows the order: minute hour day-of-month month day-of-week command. '15 2 * * 5' means minute 15, hour 2 (2 a.m.), any day of month, any month, and day-of-week 5 (Friday), which precisely matches the requirement of 2:15 a.m. every Friday.

This places 2 in the minute field and 15 in the hour field, which would schedule the job at 3:02 a.m. (15:02 in 24-hour terms is not 2:15 a.m.), reversing the minute and hour values.

This places values in incorrect fields - day-of-month and month positions are swapped with the time values, resulting in an invalid or unintended schedule.

This format misplaces the day-of-week value into the day-of-month field and leaves other fields as wildcards, which would not correctly target Fridays at 2:15 a.m.
