I'm not so sure about that. I think C might also be a valid answer - synchronous communication can be harder to follow and troubleshoot, especially in complex systems.

Yeah, that's a good point. Synchronous calls are simpler to understand, but they can make the UI feel less responsive if the API call takes a long time.

I agree with Alesia. Synchronous calls block the client until they get a response, whereas asynchronous calls allow the client to continue doing other things while waiting for the response.

Hmm, this question seems pretty straightforward. I think the answer is D - Synchronous API calls wait to return until a response has been received.
