Correct answer: TCP sends an acknowledgment for every received packet, while UDP is connectionless and uses no per-packet acknowledgments..
Why this is the answer
TCP's reliable, ordered delivery requires acknowledgments for every segment and retransmission of lost segments. This overhead introduces latency, making it less suitable for real-time applications where timely delivery is more critical than guaranteed delivery. UDP, being connectionless and lacking acknowledgments or retransmissions, has significantly lower overhead. While it doesn't guarantee delivery, its speed and efficiency make it ideal for applications like VoIP, where a lost packet is preferable to a delayed one, as the human ear can tolerate minor packet loss better than significant delays. Incorrect options describe features inaccurately or reverse them.
