This is a classic case of 'read the question carefully.' The correct answer is B, as it accurately describes the key difference between synchronous and asynchronous execution.

Haha, I bet option C was written by someone who's never used async/await before. Synchronous is the slow one, not the other way around!

Option D looks good. The synchronous execution will wait for the service to complete before returning the result, while the asynchronous execution will return immediately and deliver the result later.

I'm not sure about option C. Isn't it the other way around? Asynchronous execution is usually faster because it doesn't block the main thread.

Option B seems correct to me. The asynchronous execution service initiates the service invoking, but does not return the service execution result. That's the key difference between synchronous and asynchronous execution.
