The ______ field is used to detect errors over the entire user datagram.

A. Udp header

B. Checksum

C. Source port
D. Destination port

Explanation: Checksum field is used to detect errors over the entire user datagram. Though it is not as efficient as CRC which is used in TCP, it gets the job done for the UDP datagram as UDP doesn’t have to ensure the delivery of the packet.
