The correct answer is A. OnCalendar=Mon *-2,5,8,11-* 13:30:00. It uses the systemd OnCalendar syntax Mon -2,5,8,11- 13:30:00, which translates to “every Monday in months 2, 5, 8, and 11 at 13:30.” The other choices either misplace the month list, use invalid comma/dash placement, or repeat the calendar fields incorrectly.
