The challenge-response approach involves a handshake between the sender and receiver before any transmission takes place. This approach is suitable for connection-oriented applications, but not for connectionless applications. The overhead of the handshake would negate the chief characteristic of a connectionless transaction, which is the lack of a dedicated, continuous connection between the sender and receiver. The other options (timestamp, backward reply, and replay) do not necessarily require a handshake and could be suitable for use in a connectionless application.
