What is a characteristic of using synchronous APIs in a program?

The correct answer is A. The program waits until the value is returned by the API call. With synchronous APIs, the program waits for the API call to complete and return a value before proceeding to the next instruction. This blocking behavior ensures the result is available immediately after the call, but can delay execution if the response is slow.
