b) data protocol must have the ability of sending multiple packets without waiting for acknowledgements to be considered a reliable data transfer protocol.
c) one of the reasons UDP is said to be an unreliable protocol is it does not track whether a segment was received by the receiver.
d) the checksum field of UDP and TCP ensures a hundred percent accuracy in detecting errors in the received segment.
e) because TCP is a reliable transport protocol, the application developer can select a minimum transmission rate to be used.

Explanation / Answer

TCP cannot guarantee a minimum transmission rate. Checksum algorithms cannot give you 100% accurate results.A reliable protocol provides notification to the send while udp is considered as unreliable because it doesnt track and provides notification to the sender. Option C is the correct alternative
