Aha! B) is the way to go. Single-action timers are perfect for one-time alerts. This is an easy one. Now, if only the real exam questions were this straightforward...
I think the correct answer is B) timerService.createSingleActionTimer(alarmDate, config). It sounds like we just need to trigger the alarm once at a specific time, so a single-action timer seems like the way to go.
I agree, option B) timerService.createSingleActionTimer(alarmDate, config) seems like the best choice for triggering the alarm once at a specific time.
