C Correct answer
Explanation

If B triggers at 8:00 AM with 2-hour lead time on A, A must have COMPLETED by 6:00 AM. Since A's runtime is unspecified (could be 1 minute, 1 hour, etc.), A could have started at any time before completion. The EARLIEST A could have started is just before 6:00 AM (e.g., 6:01 AM would be too late since A must complete BY 6:00 AM, meaning A could start at 5:59 AM if runtime is 1 minute).
