I vaguely remember discussing the importance of maintainability in our studies, so I think option C makes sense. Direct calls could complicate things with JavaScript.

I feel like direct calls can lead to issues, but I can't recall all the details about why they're considered bad. It might be related to performance?

I remember a practice question that emphasized minimizing server interactions, so option B seems off to me. Synchronizing on every screen sounds excessive.
