The struggle with questions about exams is that for many of these, we don't know what the right answer is. I know which I would pick, but I've read the scrum guide multiple times and can assure you that there is no cannonically correct answer to this questions. So, I am answering with some thoughts to help you understand how I'd get to an answer, but I cannot promise that this answer is correct by any means.
If this were to happen in real life (and it does. In fact, it did yesterday for me) There are a few things I want to look at.
1) Why does Scrum advise that this occurs daily? There is the assumption in Scrum that things can change very rapidly. There is also the assumption that the team is helping each other and can best adapt to rapid change if they check in with each other at least daily.
2) Does the team feel they need these benefits from rapid checkins? Maybe the work they are doing is so by-the-book that nothing really changes day-to-day. This doesn't describe most work, but I have on occassion encountered this. On the other hand, it may be that the team doesn't really work as a team, and that is why they don't feel they need it. Or, maybe they do need it but...
3) Is the daily scrum not delivering on the benefits it is supposed to create? There may be many reasons why this is happening. Perhaps it isn't well facilitated or perhaps the team doesn't understand the purpose and therefor they aren't leveraging it effectively. I worked with one team that had a separate synch meeting an hour before their daily scrum, so of course they got no benefit out of what was essentially a second scrum.
Now, in truth, there are probably two answers that are perfectly valid, but the Scrum.org exams like to play with word use. There is one answer that is arguably valid but uses a phrase in a way that is, on its face, counter to scrum.
