Explanation

In Asynchronous Interaction pattern, the client sends a request to a service and waits until the service replies. The key characteristic of asynchronous communication is that the client doesn't block immediately - it sends the request and continues, then receives the response later (often through a callback). Option A describes one-way messaging, Option B describes synchronous communication, and Option C is incorrect because there IS a response, just not immediate.
