Which statement about synchronous and asynchronous API calls is true?
- A. Synchronous API calls must always use a proxy server
- B. Synchronous communication is harder to follow and troubleshoot
- C. Asynchronous communication uses more overhead for client authentication.

In contrast, asynchronous API calls do not block code execution; they allow the program to continue running and handle the response once it's available, typically through a callback function
